Description:
Design your own Pi HAT, attach custom circuitry and otherwise dress your Pi 3, 2, A or B with this jaunty prototyping HAT kit.
This is just the basic version of our Perma-Proto HAT. It comes with a printed circuit board and a single 2x20 GPIO Header for Raspberry Pi to put your Perma-Proto on top of your Raspberry Pi (like a nice little hat...)
Example uses:
Weather station
reef-pi
A whole heap of LED pixels with individual brightness control, for scrolling messages, animations, and more - Scroll pHAT HD!
Scroll pHAT HD packs 17x7 pixels (119 total) onto a single pHAT, and gives you full PWM brightness control over each pixel. Create beautiful animations and even anti-aliased text by taking advantage of the per-pixel brightness.
Now also available in beautiful coloured versions: red, orange, yellow, green, blue, and pink!
Use Scroll pHAT HD as a scrolling message display for your tweets, the weather or the news, or use it as a 17-band spectrum analyser for your audio. There's even enough pixels for simple games like Tetris, Pong, or snake.
Our handy one-line installer will install the Scroll pHAT HD Python library for you. We've included a bunch of examples too, to show off what you can do with Scroll pHAT HD.
Our software does not support Raspbian Wheezy.

Description:
Great for small 12 volt DC solar panel LED Lighting systems to conserve battery power; also well suited for occupancy LED lighting control and security LED Lighting systems
Specifications:
Raspberry Pi and case not included
Great for including a colourful character display and button inputs on your Raspberry Pi based projects!
Includes a 16x3 character LCD display, 6-zone RGB LED backlight, bar graph, and six capacitive touch buttons all in one slim package.
It's ideal for controlling your internet radio or home automation projects.
Features
Software
Our Display-O-Tron Python library will get you going in a jiffy, and makes controlling Display-O-Tron HAT really easy.
We've included examples showing you how to use the backlight, bar graph LEDs, and touch buttons, as well as more advanced examples showing you how to create menus, games and even an internet radio!
Notes
If you want to keep your Pi in a case, we recommend the Pibow Coupé case as it will allow you to still use the capacitive touch buttons.

Advanced / Display-O-Tron 3This display is made of 128x64 individual white OLED pixels, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness!
This breakout can be used with either an SPI or I2C interface - selectable by soldering two jumpers on the back. The design is completely 5V-ready, with an onboard regulator and built in boost converter. It's easier than ever to connect directly to your 3V or 5V microcontroller without needing any kind of level shifter!
TheRaspberryPiGuy has done an *excellent* video on getting this display running with your Pi.
Guy Carpenter has a guide for using OLEDs like this one with the Raspberry Pi it's well worth a read!
Using this display with a Raspberry Pi? Check out Adafruit's SSD1306 OLED display guide.
Adafruit have provided a detailed tutorial and example code in the form of an Arduino library for text and graphics. You'll need a microcontroller with more than 1K of RAM since the display must be buffered.
On the Raspberry Pi, Adafruit now have a Python library available that works with these displays in both i2c and SPI mode.
You can download the Adafruit SSD1306 OLED display Arduino library from github which comes with example code. The library can print text, bitmaps, pixels, rectangles, circles and lines. It uses 1K of RAM since it needs to buffer the entire display but its very fast! The code is simple to adapt to any other microcontroller.

Description:
This minimal camera for the Pi Zero (or Pi Zero W, WH, 2W) is perfect for small camera projects where space is at a premium.
The sensor is 5MP, and the whole shebang is mounted on a flexible circuit board. As such, a little care is needed when handling, just like the connector on the Pi Zero. Easy there, Lennie!
Otherwise it's an economical and svelte solution for bird box cameras, body-cams, home security, and simple computer vision projects.

Please Note: The Raspberry Pi board is not included
Description:
Our all-new case that we designed from the ground up for the Pi 4. You can learn more about the case and the design process in the blog.
The SecurePi Case was designed to work with the Pi 4. With optional SD and USB/Ethernet/HDMI covers as well as its discrete cooling vents, this functional and attractive case will complement any Raspberry Pi 4.
Unique features:
Turn your Raspberry Pi into a retro games console! Picade X HAT includes joystick and button inputs, a 3W I2S DAC/amplifier, and soft power switch. Nice!
Picade X HAT is now Raspberry Pi 4 compatible, with USB-C power!
This HAT has all the same great features as the original Picade HAT but now has no-fuss female Dupont connectors to hook up your joystick and buttons.
Simply pop Picade X HAT onto your Pi, plug a USB-C power supply into the connector on the HAT (it back-powers your Pi through the GPIO, so no need for a separate power supply), wire up your controls, and install our driver! It's ideal for your own DIY arcade cabinet builds, or for interfaces that need big, colourful buttons and sound.
FeaturesThe I2S DAC blends both channels of digital audio from the Raspberry Pi into a single mono output. This is then passed through a 3W amplifier to power a connected speaker.
The board also features a soft power switch that allows you turn your Pi on and off safely without risk of SD card corruption. Tap the connected button to start up, and press and hold it for 3 seconds to fully shutdown and disconnect power.
SoftwareWe've put together a simple one-line installer that'll get everything set up on your Picade X HAT, the controls, safe shutdown, and audio. Open a terminal and type curl https://get.pimoroni.com/picadehat | bash
to run the installer. You'll need to reboot once the installation is complete, if it doesn't prompt you to do so.
Our software does not support Raspbian Wheezy
NotesWith USB-C power connected through Picade X HAT you'll need either to tap the connected power button or the button marked "switch" on the HAT to power on your Pi.
