Please note: Raspberry Pi not included

The Explorer HAT and Explorer HAT Pro are the perfect prototyping side-kicks for your Raspberry Pi!

We've added a heap of useful input and output options that will take your projects to the next level. Great for driving motors, using analog sensors, interfacing with 5V systems, and touch (even fruit based!) interfaces.

It's compatible with Raspberry Pi 2, Pi 3, B , and A and comes fully assembled.

Features:

• Four buffered 5V tolerant inputs
• Four powered 5V outputs (up to 500mA!)
• Four capacitive touch pads
• Four capacitive crocodile clip pads
• Four coloured LEDs
• PRO ONLY Four analog inputs
• PRO ONLY Two H-bridge motor drivers
• PRO ONLY A heap of useful (unprotected) 3v3 goodies from the GPIO
• A mini breadboard on top!

5V tolerant inputs - Hook up your Pi to accept input from 5V systems (like Arduino Uno/Leonardo or 5V Trinkets). We've used a 5-channel buffer that will accept anything from 2V-5V as logic high.

5V powered ouputs - The onboard darlington array can supply up to 500mA per channel (but you'll be limited to driving around 1A total from the board). Ideal for stepper motors, solenoids, and relays.

Eight capacitive inputs - Four along the front edge for touch input (labelled 1, 2, 3, 4) and four up the side for attaching crocodile clips to objects (such as fruit, or tin foil) for experimentation!

Four coloured LEDs - Independently controllable LEDs (red, green, blue, and yellow) that make great status indicators.

Four analog inputs (pro only) - A tidy way to integrate analog signals into your project.

Two H-Bridge motor drivers (pro only) - Drive two 5V motors bidirectionally with up to 200mA per channel. Ideal with our micro-metal gear-motors to create the perfect little buggy! You can even soft-PWM for full speed control.

Raspberry Pi Zero not included!

Absolutely no soldering required! All that's needed is a few gentle taps with a hammer and bazinga! Your header is securely attached to your Pi Zero or pHAT.

If your soldering isn't quite up to scratch, or you just don't own a soldering iron yet, then these nifty hammer headers might be just the job. They come in male and female flavours, and use crafty little retaining nubbins to grip tightly into the holes on the PCB.

The installation jig kit contains two acrylic base pieces, onto which your Pi Zero or pHAT sits, two nylon bolts, an acrylic top piece onto which you hammer, and both a male and female header. Make sure you carefully read our guide for fitting hammer headers.

What's in the box?

2 x Nylon nuts and bolts
1 x Installation Jig
1 x Male header
1 x Female header

Resources

We strongly recommend using our installation jig! If you want to try without it then godspeed to you but it is a delicate and tricky process! The female headers are simpler to insert than the male headers as you can hammer straight onto the plastic of the header, but the male ones are particularly tricky without the jig.

Please note: we can't be held responsible for any damage that you may cause to your Pi Zero, pHAT, fingers, or headers while fitting them. If you follow our guide carefully then you should be fine. If this worries you, then get yourself a soldering iron instead!

Loose Male hammer headers are also available.

Tutorial on using the jig

Watch our demo of how to fit the hammer headers on Bilge Tank, below.

Our SHIMs (Shove Hardware in the Middle) are a new range of boards designed to be small, affordable, and handy. They're just 1mm thick (the bare board, not including mounted components) and designed to be soldered straight onto the GPIO pins of your Pi, if you wish, so that you can use them with HATs and pHATs on top.

Usage

Just plug your micro-USB power supply into the micro-B connector on OnOff SHIM, and then press the button once to switch on power and boot up your Pi. After installing our software (details below), you can press the button again to initiate a clean shutdown and completely cut the power to your Pi.

Features

• super-small SHIM-format board
• 1mm thick PCB
• can be used with HATs and pHATs
• corner-mounted push button for on/off
• micro-B connector for power supply
• red status LED
• optional breakout pins to connect an external momentary button
• 2x6 female header included
• software daemon to shutdown cleanly
• requires soldering

Software

We've put together a one-line-installer to install the clean shutdown daemon. It watches the state of BCM pin 17 and, when pulled low (pressed), it initiates a clean shutdown. Last thing, just before your Pi shuts down, BCM pin 4 is pulled low to completely cut power to your Pi.

To install the software, open a terminal and type curl https://get.pimoroni.com/onoffshim | bash to run the one-line-installer.

What's going to protect your beloved Raspberry Pi from an onslaught of rainbow-coloured fusion? That's right, it's Unicorn HAT.

Sporting a matrix of 64 (8 x 8) RGB LEDs and powered directly from the Pi, this is the most compact pocket aurora available.

Unicorn HAT provides a wash of controllable colour that is ideal for mood-lighting, 8x8 pixel art, persistence of vision effects, status indications, or just blasting colour into your surroundings.

The MagPi said that Unicorn HAT was "one of the coolest HATs around"

Features

• 64 RGB LEDs (WS2812B)
• LED data driven via DMA over PWM
• Unicorn HAT pinout
• Compatible with Raspberry Pi 3, 2, B , A , Zero, and Zero W
• Python library
• Comes fully assembled

Software

We've put together a Unicorn HAT Python library to make it a breeze to use, including lots of beautiful examples of what it can do.

Notes

• Warning: WS2812 LEDs are bright enough to cause eye pain, do not look at them directly when brightly lit. We recommend the use of a diffuser.
• Photo-sensitivity warning: flashing, strobing, and patterns of lights may cause epileptic seizures. Always take care and immediately stop using if you feel unwell (dizziness, nausea, affected vision, eye twitching, disorientation).
• Power: Unicorn HAT requires a >2A microUSB power supply for your Pi. We recommend the official Raspberry Pi power supply.
• Compatibility (audio): as Unicorn HAT uses PWM and GPIO18, it will interfere with analogue audio playback (random colour patterns and flickering). HDMI should work just fine!

Please note: we can't be held responsible for any damage that you may cause to your Pi Zero, pHAT, fingers, or headers while fitting them. If you follow our guide carefully then you should be fine. If this worries you, then get yourself a soldering iron instead!

Software

As ever, we've made a super-simple to use Python library to take advantage of Automation HAT's multitudinous functions, with examples to get you started.

Our input, output and relay examples show you how to read the analog and digital inputs, switch the outputs on and off, and control the relays.

Notes

• We recommend you use a set of brass M2.5 standoffs with Automation HAT to avoid pins contacting the HDMI port if the HAT is pushed down
• Loads for the buffered outputs should be switched on the ground side, i.e. 12/24V (from supply) -> load -> output terminal -> ground (from supply)
• The relays can tolerate up to 2A each and should be switched on the high side

Power-up your TV with Picade Console! It's a compact, Raspberry Pi-powered retro games machine with authentic arcade controls that plugs right into your TV, monitor, or other HDMI display.

Picade Console is fight stick-style arcade console that riffs off our new Picade with the same retro feel, same joystick and buttons, dedicated power button, and driven by the same powerful combo of the Raspberry Pi and Picade X HAT. It's beautifully packaged, comes with stickers and a neon-infused A3 Picade Console poster, and full assembly instructions.

It comes in kit form and takes an hour or two to build. The enclosure is made from powder-coated MDF and acrylic, giving it an authentic arcade look and feel. All you'll need to add is a Raspberry Pi, power supply, HDMI cable, and micro-SD card.

What's new!?

Picade Console is more compact and easier to build, but has a bunch of new features liked a dedicated power button, better cable routing out the back of the console with a panel-mount micro-USB connector for power, and slick new artwork.

The new buttons in Picade are lower profile, and the new joystick has a single connector rather than the eight spade connectors on our previous Picade joystick.

Picade X HAT is all-new and packed full of useful features. We've moved from more fiddly screw terminals to simple DuPont connectors that just push in, and the speaker terminals are the same easy push-fit connectors that we use on pHAT BEAT.

There's dedicated power management on-board Picade X HAT; just plug your micro-USB power supply into the HAT and it'll power your Pi through its pins. The power button connected to the HAT means that once your Pi is safely shutdown, the power will be cut completely to the Pi. A simple press of the power button will boot your Picade Console up again.

Software setup

We recommend the RetroPie operating system for your Picade. You can download it from the RetroPie website and then burn it to a micro-SD card with Etcher.

Connect a USB keyboard to your Pi, and connect to Wi-Fi in the RetroPie menu. Press F4 to exit to the terminal and then type curl https://get.pimoroni.com/picadehat | bash to run the Picade HAT installer.

Reboot your Pi, if it doesn't prompt you to. Press the "Alt" key on your keyboard and then select "Configure input" to configure your Picade Console's controls. You'll find that the sound and power button should both be working now too!

Use Four Letter pHAT to display... four letter words. Not that sort!

Pi ZERO and case not included!

Four Letter pHAT has four 14-segment displays that you can use to display text, numbers, and a host of other characters. Its LEDs are a beautiful retro green, just like you old digital alarm clock. They're driven by the HT16K33 chip over I2C.

It's perfect as a readout for your projects, displaying temperatures, times, etc. and becomes really useful when combined with some of our other boards like Enviro pHAT or Explorer pHAT to display their sensor values.

Features

• Four 14-segment displays with green LEDs
• HT16K33 driver chip
• Compatible with Raspberry Pi 3, 2, B , A , Zero, Zero W
• Python library
• Female header and display pins require soldering

Software

Our handy one-line installer will install the Four Letter pHAT Python library for you. We've included a bunch of examples too, to show off what you can do with Four Letter pHAT; things like a clock, a countdown timer, or CPU activity monitor.

Explorer pHAT is the perfect prototyping side-kick for your Raspberry Pi!

A more diminutive version of our popular Explorer Hat Pro, it's cheaper and designed to fit perfectly on a Raspberry Pi Zero!

We've added a heap of useful input and output options that will take your projects to the next level. Great for driving motors, using analog sensors, and interfacing with 5V systems (like Arduino).

Make your Raspberry Pi seriously cool with Fan SHIM! This 30mm no-solder, controllable CPU fan with RGB LED and tactile switch will give your Raspberry Pi significantly better thermal performance.

Fan SHIM uses a friction-fit header, so it just slips onto your Pi's pins and it's ready to go, no soldering required! Note that, due to the height of the fan, if you want to use HATs or pHATs with Fan SHIM, then you'll need to use a booster header.

The fan can be controlled in software, so you can do crafty things like toggle it on when the CPU reaches a certain temperature. Use the LED as a handy visual indicator to show fan status, CPU load/temperature, whatever! The tactile switch can also be programmed, so you can use it to toggle the fan on or off, or to switch between temperature-triggered or manual mode.

Oh, and it's compatible with our new Pibow Coupé 4 case for Raspberry Pi 4!

Features

• 30mm 5V DC fan
• 4,200 RPM
• 0.05 m³/min air flow
• 18.6 dB acoustic noise
• Friction-fit header
• No soldering required
• RGB LED (APA102)
• Tactile switch
• Basic assembly required
• Compatible with Raspberry Pi 4 (and 3 B , 3 A )
• Python library and daemon

Kit contains

• Fan SHIM PCB
• 30mm 5V DC fan with JST connector
• M2.5 nuts and bolts

Assembly

Assembly is really easy, and will take less than two minutes.

1. With the component side of the PCB facing upwards, push the two M2.5 bolts through the holes from below, then screw on the first pair of nuts to secure them and act as spacers.
2. Push the fan's mounting holes down onto the bolts, with the cable side of the fan downwards (as pictured) and the text on the fan upwards. Attach with another two nuts.
3. Push the fan's JST connector into the socket on Fan SHIM.

Software

Our Python library lets you control the fan (on/off), RGB LED, and switch. There's a handful of examples to show you how to use each feature, and a script to install a daemon (a service that runs in the background) that runs the fan in automatic mode, triggering it on or off when the CPU reaches a threshold temperature, with a manual override via the tactile switch.

Notes

• When mounting or detaching the fan, or assembled Fan SHIM, do not push on the fan itself, as it is liable to break.
• Not heatsink-compatible!
• Dimensions: 45x39x11mm

Monitor your world with Enviro for Raspberry Pi! There's a whole bunch of fancy environmental sensors on this board, and a gorgeous little full-colour LCD to display your data. It's the perfect way to get started with citizen science!

Designed for environmental monitoring, Enviro  lets you measure air quality (pollutant gases and particulates*), temperature, pressure, humidity, light, and noise level. When combined with a particulate matter sensor*, it's great for monitoring air quality just outside your house (more information below), or without the particulate sensor you can use it to monitor indoor conditions.

Enviro  is an affordable alternative to environmental monitoring stations that can cost tens of thousands of pounds and, best of all, it's small and hackable and lets you contribute your data to citizen science efforts to monitor air quality via projects like Luftdaten.

Features

• BME280 temperature, pressure, humidity sensor (datasheet)
• LTR-559 light and proximity sensor (datasheet)
• MICS6814 analog gas sensor (datasheet)
• ADS1015 analog to digital converter (ADC) (datasheet)
• MEMS microphone (datasheet)
• 0.96" colour LCD (160x80)
• Connector only for particulate matter (PM) sensor*(sensor is not included)
• pHAT-format board
• Fully-assembled
• Compatible with all 40-pin header Raspberry Pi models
• Pinout
• Python library
• Dimensions: 65x30x8.5mm

A couple of nice little extras... there's a spare ADC channel broken out on a header if you want to connect another analog sensor, along with I2C pins in the right configuration for plugging one of our Pimoroni I2C breakouts onto!

Citizen science air quality monitoring

We've developed this board in collaboration with the University of Sheffield, with the aim of letting you contribute real-time air quality data from your local area to open data projects like Luftdaten.

The alarming drop in our air quality is something that's really important to understand. Devices like Enviro  allow fine-grained, detailed datasets that let us see shifts in air quality through time and across different areas of cities. The more devices that contribute data, the better quality the dataset becomes.

Particulate matter (PM) is made up of tiny particles that are a mix of sizes and types, like dust, pollen, mould spores, smoke particles, organic particles and metal ions, and more. Particulates are much of what we think of as air pollution. They can be measured, in size and quantity, by particulate matter sensors like the PMS5003 that you can connect to Enviro .

The analog gas sensor can be used to make qualitative measurements of changes in gas concentrations, so you can tell broadly if the three groups of gases are increasing or decreasing in abundance. Without laboratory conditions or calibration, you won't be able to say "the concentration of carbon monoxide is n parts per million", for example.

Temperature, air pressure and humidity can all affect particulate levels (and the gas sensor readings) too, so the BME280 sensor on Enviro  is really important to understanding the other data that Enviro outputs.

We've got a tutorial (coming soon) that shows you how to use Enviro  and a few easily-available bits to build the board into a weather-proof housing that you can mount outside your house to monitor local air quality.

Indoor monitoring

As well as outdoor air quality monitoring, Enviro  is really good for indoor monitoring too. The temperature, humidity, light, and noise readings can be used to keep track of conditions in your home and, combined with the LCD to display the data and the proximity sensor for interaction, it makes an ideal headless monitoring device.

Why not combine it with some IoT smarts like an Alexa skill so that you can ask what the temperature or humidity is? Or you could set up a trigger action with IFTTT that turns your Philips Hue lights on when the light level drops below a certain level. There's loads of possibilities!

What's in the box?

1 x Enviro board only

Resources

We've put together a Python library to control all the parts of your Enviro . There's a bunch of examples for each of the individual parts, an all-in-one example that shows you the data from Enviro 's sensors in a visual way. There's also an example that shows you how to contribute data to Luftdaten (requires particulate matter sensor).

Getting Started

Have a read through our (exhaustive!) Getting Started with Enviro  tutorial that walks you through how to install the software, how to run the code examples, and how to use the Enviro  Python library.

• There is a DAC enable pin—BCM 25— that must be driven high to enable the DAC. You can do this by adding gpio=25=op,dh to the /boot/config.txt file.
• The buttons are active low, and connected to pins BCM 5, 6, 16, and 20
• The display uses SPI, and you'll need to enable SPI through the Raspberry Pi configuration menu.
• If you want to use these boards with a Pibow Coupé case (either for the Zero / Zero W or Pi 4), then you'll need to use a booster header to raise it up a little.

Pump out some mini beats with Pirate Audio Speaker! This diminutive sound system has an I2S DAC, amp, mini mono speaker, high-res display, and playback control buttons.

Pirate Audio Speaker is perfect for making a Lilliputian radio, sound effect player, or even as a teeny-weeny games console! The built-in 1W speaker isn't the loudest but it's great fun for lots of projects. The display and playback buttons let you control your audio or sound effects in a jiffy. Use our Pirate Audio software (more info below) to play local audio files (MP3, FLAC, etc) or stream from services like Spotify.

Pirate Audio is a range of all-in-one audio boards for Raspberry Pi, with high-quality digital audio, beautifully-crisp IPS displays for album art, tactile buttons for playback control, and our custom Pirate Audio software and installer to make setting it all up a breeze.

Software

Our Pirate Audio software and installer installs the Python library for the LCD, configures the I2S audio and SPI, and then installs Mopidy and our custom Pirate Audio plugins to display album art and track info, and to use the buttons for playback control.

Here's how to get started:

1. Set an SD card up with the latest version of Raspbian.
2. Connect to Wi-Fi or a wired network.
3. Open a terminal and type the following:
   
   git clone https://github.com/pimoroni/pirate-audio
cd pirate-audio/mopidy
sudo ./install.sh
   
   
4. Reboot your Pi

You can find more detailed instructions here: https://github.com/pimoroni/pirate-audio/tree/master/mopidy

Notes

Note that our installer, linked above, does all of the below for you, but if you're an intrepid hacker then you might need to know this stuff!

• The DAC can be configured by adding dtoverlay=hifiberry-dac to the /boot/config.txt file.
• There is a DAC enable pin—BCM 25— that must be driven high to enable the DAC. You can do this by adding gpio=25=op,dh to the /boot/config.txt file.
• The buttons are active low, and connected to pins BCM 5, 6, 16, and 20
• The display uses SPI, and you'll need to enable SPI through the Raspberry Pi configuration menu.
• If you want to use these boards with a Pibow Coupé case (either for the Zero / Zero W or Pi 4), then you'll need to use a booster header to raise it up a little.

Monitor air pollution cheaply and accurately with this matchbox-sized particulate matter (PM) sensor from Plantower! It senses particulates of various sizes (PM1, PM2.5, PM10) from sources like smoke, dust, pollen, metal and organic particles, and more.

Pair this particulate matter sensor with our Enviro plus and build your own air quality monitoring station to contribute to citizen science. Just plug the cable into the sensor and then into the connector on the underside of Enviro plus, and away you go!

The sensor has a small fan that sucks air through the sensor and past a laser that can detect both the number (and hence concentration) and size of particles in the surrounding air.

• Plantower PMS5003 Particulate Matter (PM) Sensor (datasheet)
• Detects PM1, PM2.5, PM10 particulates
• 15cm Picoblade cable
• UART serial interface
• Python library
• Dimensions: 50x38x21mm

Our Python library for the PMS5003 sensor lets you read PM1, PM2.5, and PM10 in both standard and environmental units, and numbers of particles of various sizes: >0.3, >0.5, >1.0, >2.5, >5, and >10um.

Note that if you're using this sensor with Raspberry Pi, then you'll need to make a couple of changes to its configuration. Type sudo raspi-config in the terminal and then under "Interfacing options" and "Serial" disable the login shell and enable the serial port hardware. Edit your /boot/config.txt file and add the lines enable_uart=1 and dtoverlay=pi3-miniuart-bt to the bottom of the file.

Our Enviro plus installation script will do all of this configuration for you.

There's a blue protective film that covers the metal casing of the sensor, and you can peel this off before use.

Scoring very highly in the Pimoroni "things on our desk that make people say ooo" rankings, RGB Keypad Base equips a Pico with an eye-catching 4x4 silicone keypad, fully loaded with addressable APA102 LEDs so that each key can be illuminated in any colour that your little unicorn heart desires. It's all mounted on a sturdy base with rubber feet to keep it nice and level, with a handily labelled landing area for your Pico. We've broken out the full set of Pico pins to make it easy to connect up other hardware as well.

Connect your Pico project to another computer via USB for a beautiful macro keypad or a tidy midi controller. RGB Keypad Base would also work well in any project that would benefit from having fancy light up buttons as inputs - a code protected door lock perhaps, a disco dance floor for your fingers or a Simon Says style game with which to taunt your friends.

A Raspberry Pi Pico is not included - click here if you'd like to buy one!

Your Pico will need to have male headers soldered to it (with the pins pointing downwards) to attach to our add-on boards.

Features

• 4x4 silicone keypad with conductive buttons
• 16 x APA102 addressable RGB LEDs (datasheet)
• Keypad buttons are connected via a TCA9555 IO expander (I2C address: 0x20).
• Labelled landing area with female headers for attaching your Pico, with broken out pins.
• Compatible with Raspberry Pi Pico.
• Some assembly required!
• No soldering required (as long as your Pico has header pins attached).
• Dimensions: approx 60mm x 101mm x 16mm (L x W x H, assembled)
• C/C and MicroPython libraries

Includes

• 1x Pico RGB Keypad Base
• 1x (reversible) square retainer plate
• 1x silicone keypad
• M2 8mm bolts and nuts
• 4x rubber feet

Getting started

Turn the larger board over, and attach the little rubber feet to the paw print spaces on the bottom.

Flip it over again, and pop the silicone keypad over the buttons so the tabs fit into the holes. You can then slot the retainer plate over the top of the keys, matching up the key markings with those on the base board. You can install the retainer plate either way up, depending on whether you prefer it patterned or plain!

Poke the M2 bolts through the holes in the mounting plate (from the top) and screw on the nuts to keep all the layers sandwiched together. The bolts only need to be tightened up enough to keep the layers in place - if you find that the keys are hard to push or that the silicone layer is bulging out of the sides you might want to slacken them off a bit.

The labels on the base will show you which way round to attach your Pico - just match up the USB port to the markings on the board.

The easiest way to get started is by downloading and copying our custom MicroPython uf2 to your Pico, it includes all the libraries you'll need to use our add-ons. Click here for our beginner friendly tutorial!

You can find C examples here and MicroPython examples here.

What's in the box?

1 x Pico Keypad

Built especially to showcase the low cost, feature-rich RP2040 chip on the Raspberry Pi Pico, this board has VGA output, an SD card slot, digital I2S audio output, and more!

Based on the reference design by Raspberry Pi, our Pimoroni Pico VGA Demo Base is a great way to start experimenting with Raspberry Pi Pico/RP2040. It's the perfect way to demo of some of the fun things you can achieve with the RP2040 microcontroller such as generating a solid VGA output without taxing the CPU at all!

• Amaze your friends by showing them you still own a D-sub cable!
• Bask in the glory of 15-bit analog video!
• Get teary eyed over the warm, authentic, RC filtered PWM audio!

This board will run the various video example programs that Raspberry Pi have put together to demonstrate features of the RP2040.

Please note that VGA Demo Base only currently works with the C/C Pico SDK!

A Raspberry Pi Pico is not included - click here if you'd like to buy one!

Your Pico will need to have male headers soldered to it (with the pins pointing downwards) to attach to our add-on boards.

Features

• 15-pin VGA (D-sub) connector
• PCM5100A DAC for line out audio over I2S (datasheet)
• PWM audio output
• SD card slot
• Reset button
• Female headers to install your Raspberry Pi Pico
• Three user-controllable switches
• Rubber feet
• Compatible with Raspberry Pi Pico
• No soldering required (as long as your Pico has header pins attached)
• Programmable with C/C

The pin-out of our board is the same as Raspberry Pi's reference board, you can find it in chapter 3 of Hardware Design with RP2040 along with more general info about the VGA reference board.

To run the audio and video examples in Raspberry Pi's experimental repos, first make sure you have up to date versions of pico-extras and pico-playground. When building the examples, you will need to specify the board configuration so that the examples use the correct pins. You can do this by creating a new build directory and then specifying the board definition when using cmake:

cmake -D"PICO_BOARD=vgaboard" ..

There's more details on about how to build applications with custom board configurations in Appendix D / page 267 of the C/C SDK documentation.
