Raspberry Pi Sense HAT (Sense Hat)

The Sense HAT is an add-on board for Raspberry Pi, made especially for the Astro Pi mission! It’s going to the International Space Station in December 2015 – and is now available to buy from PiShop.

The Sense HAT has an 8×8 RGB LED matrix, a five-button joystick and includes the following sensors:

  • 3D Gyroscope
  • Accelerometer (Yaw, Pitch & Roll)
  • Magnetometer
  • Temperature
  • Barometric Pressure
  • Humidity

The Raspberry Pi Foundation have also created a Python library providing easy access to everything on the board.

Sensing Elements Technical Specification:

Pressure / Temperature (ST Micro LPS25H)
– 24-bit pressure measurement resolution (260hPa to 1260hPa)
– 16-bit temperature measurement resolution (0-125°C)
Datasheet

Humidity / Temperature (ST Micro HTS221)
– 16-bit humidity measurement resolution (0-100% relative humidity)
– 16-bit temperature measurement resolution (0-60°C)
Datasheet

Acceleration/Gyroscope/Magnetic field (ST Micro LSM9DS1)
– 9 degrees of freedom (X, Y, Z independent axes for all sensors)
– ±16 g acceleration measurement range
– ±16 gauss magnetometer measurement range
– ±2000 dps (degrees per second) gyroscope measurement range
Each of these measurement channels has 16 bits of resolution.
Datasheet

All of these sensors have features for periodic sampling of sensor values, complete with internal FIFO storage. The LPS25H and HTS221 have maximum sample rates of 25 per second, the LSM9DS1 has a maximum sample rate of 952Hz

LED Matrix
The LED matrix is driven by a combination of a constant-current LED driver and an Atmel ATTiny88 running a custom firmware that delivers an 8×8 display with 15-bit resolution RGB colour. If you want to get into the gory details, the AVR firmware is available on Github.

Joystick
The Atmel is responsible for sampling the joystick. We didn’t have enough pins left on the Atmel to dedicate the five that we needed to sample the joystick axes independently, so they’ve been spliced into the LED matrix row selects. The joystick gets updated at approximately 80Hz, which is the scan rate of the LED matrix.

All of the sensors (and the base firmware for the Atmel) are accessible from the Pi over I2C. As a fun bonus mode, the SPI peripheral on the Atmel has been hooked up to the Pi’s SPI interface – you can reprogram your HAT in the field! We use this method to get the firmware into the Atmel during production test – and we leave it unprotected so you can substitute the stock firmware to get it to do whatever you want. Seriously. First person to turn this sensor HAT into a quadcopter controller HAT wins a cookie from me.

Getting Started

Connect your Sense HAT to the Raspberry Pi via the 40 GPIO Pins.You will then need to install the software:

Open up a terminal and run the following command:

wget -O - http://www.raspberrypi.org/files/astro-pi/astro-pi-install.sh --no-check-certificate

When the install has finished you will need to reboot your Raspberry Pi!

SparkFun Logic Level Converter Bi-Directional (3A4 Sparkfun logic level converter )

If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The SparkFun bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time.

This level converter also works with 2.8V and 1.8V devices. What really separates this Logic level converter from our previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the same channel. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side.

The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the ‘HV’ pin, low voltage (3.3V for example) to ‘LV’, and ground from the system to the ‘GND’ pin.

Raspberry Pi GPS HAT (1A4 GPS hat green)

This is a Raspberry GPS HAT expansion board designed specifically for the Raspberry Pi B+, A+ and Raspberry Pi 2 Model B!  It's a simple to install and use GPS module, that utilises the Raspberry Pi the serial ports (UART) for communication. The board is compliant with Raspberry Pi HAT specification, and includes a 2x20 way header and stand-offs to provide a robust solution to Raspberry Pi GPS function.

We also have cases available for the Raspberry Pi and GPS HAT combination in Clear, and you'll probably need an external Antenna to get going!

It's great for accurate timing applications or general applications that require GPS information. It's equipped with the latest Ublox MAX-M8Q low power, high performance positioning module and features an RTC Crystal for timing applications, making it more than adequate for a Pi based NTP Server. Its worth noting the module can, with a serial command, be placed in “Stationary” dynamic mode which is the default mode for the much more expensive timing modules.To facilitate PPS, the time pulse output is connected to GPIO18, so you can utilise this board to give NTP PPS discipline. 

The board features an SMA Female connector for an active patch antenna power, PPS LED's, and an on board 6 hour supercap which can be used to retain any custom settings in the event of power loss.

Please Note. This board is NOT compatible with the original Raspberry Pi A and B boards.

Please Note. This board has firmware version 2.01 and is currently unable to receive Galileo signals.

Features:

  • Raspberry Pi HAT Compliant GPS Module
  • MAX-M8Q GPS Chipset
  • Utlises Pi Serial UART Connection
  • PPS connected to GPIO18 (Pin 12)

VGA 666 Adapter Board For Raspberry Pi 3 Model B 2B B+ A+ (2C4 vga board red soldered)
Description:

It is a neat and very useful solution for using a VGA display/monitor with your Raspberry Pi and is cheaper than an HDMI to VGA adapter or similar. The VGA connection is driven natively in hardware over the GPIO pins (using a parallel interface) and uses around the same CPU load as the HDMI connection on board. It is capable of displaying 1080p60 VGA video with no CPU load. It is also possible to drive this interface at the same time as the HDMI connection, so a dual screen set up is also possible.

This add-on board uses all but 6 of the GPIO pins so it may not be possible to use other add-on boards at the same time as the VGA adapter. You should disable all of the GPIO pin's function so that it can work properly.

We strongly recommend that you use 800x600 resolution. The highly resolution will slow down your Pi and use more RAM.

Feature:

- Support for Raspberry Pi 3B / 2B / B+ / A+
- The VGA output supports resolution:from 640 x 480 up to 1920 x 1024 at 60fps.
- With 6 bits per channel you have a maximum of 262144 colours.
- No soldering required.
- Easy to setup.
- Easy to configure.
- Dimension: 64.00mm x 32.3mm
- Net weight: 16.5g

Adafruit DC & Stepper Motor HAT - Mini Kit (1D4 Adafr DC & Step Mini Kit)

Let your robotic dreams come true with the new DC+Stepper Motor HAT from Adafruit. This Raspberry Pi add-on is perfect for any motion project as it can drive up to 4 DC or 2 Stepper motors with full PWM speed control.

Raspberry Pi and motors are not included.

Since the Raspberry Pi does not have a lot of PWM pins, we use a fully-dedicated PWM driver chip onboard to both control motor direction and speed. This chip handles all the motor and speed controls over I2C. Only two pins (SDA & SCL) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or HATs to the same pins.

In fact, you can even stack multiple Motor HATs, up to 32 of them, for controlling up to 64 stepper motors or 128 DC motors (or a mix of the two) - just remember to purchase and solder in a stacking header instead of the one we include.

Motors are controlled by TB6612 MOSFET drivers with 1.2A per channel and 3A peak current capabilitya big improvement over L293D drivers and there are built-in flyback diodes as well.

We even had a little space so we added a polarity protection FET on the power pins and a bit of prototyping area. And the HAT is assembled and tested here at Adafruit so all you have to do is solder on the included 2x20 plain header and the terminal blocks.

Lets check out these specs again:

  • 4 H-Bridges: TB6612 chipset provides 1.2A per bridge (3A peak) with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 13.5VDC.
  • Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution)
  • Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping.
  • Big terminal block connectors to easily hook up wires (18-26AWG) and power
  • Polarity protected 2-pin terminal block and jumper to connect external 5-12VDC power
  • Works best with Raspberry Pi model A+, B+, Pi 2 B or Pi 3 B.
  • Install the easy-to-use Python library, check out the examples and you're ready to go!

Comes with an assembled & tested HAT, terminal blocks, and 2x20 plain header. Some soldering is required to assemble the headers on. Stacking header not included.

Raspberry Pi, motors, and battery pack are not included but we have lots of motors in the shop and all our DC motors, and stepper motors work great. Check out Adafruit's detailed tutorial for tons of info including schematics, wiring diagrams, python libraries and example walkthroughs.

Adafruit ADS1015 12-Bit ADC (3A4 ADS1015 12-Bit ADC)

The Raspberry Pi does not feature an Analog-to-Digital Converter (ADC), so if you want to measure analogue singals, you'll need this 12-Bit ADC!

The Adafruit 4-Channel I2C 12-Bit ADC is a high-precision ADC and features the ADS1015 chip, which provides 12-bit precision at 3300 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier,with up to x16, to help boost smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 12 bit converter. 

The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet and interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5 in downloads below) so you can have up to 4 ADS1015's connected on a single 2-wire I2C bus for 16 single ended inputs. 
 
To get you started, we have example code for the Raspberry Pi - Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller's I2C port and run the example code to start reading data.
 
The Adafruit 4-Channel I2C 12-Bit ADC Features:
  • Wide Supply Range: 2.0V to 5.5V
  • Low Current Consumption: Continuous Mode: Only 150µA Single-Shot Mode: Auto Shut-Down
  • Programmable Data Rate: 128SPS to 3.3kSPS
  • Internal Low-Drift Voltage Reference
  • Internal Oscillator
  • Internal PGA
  • I2C Interface: Pin-Selectable Addresses
  • Can run from 2V to 5V power/logic
  • Measures a large range of signals and is super easy to use.
  • 12-bit precision at 3300 samples/second over I2C.
  • Configurable as 4 single-ended input channels, or two differential channels.
  • Includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range.
  • Breakout Board equipped with ferrites to keep the AVDD and AGND quiet

ModMyPi PiOT Relay Board (2A3 MMP PiOT relay)

Raspberry Pi board not included

The ModMyPi PiOT (Pi of Things) relay board is smart! Not quite Skynet smart, so you can tell John Connor to stay at home and play with his Raspberry Pi. But it's much smarter than your average relay board! We've created a Raspberry Pi Relay Board that does away with the complicated wiring and fiddly jumper configuration of your standard relay board, and bundles that control into an on-board PIC, making configuration faster, easier and safer. The PiOT relay board can be connected directly on top of the Pi, or via a GPIO ribbon cable (not included), and also features mounting points for the Raspberry Pi Zero. Each is board is fully assembled, and ready to plug and play! We also stock cases for the Raspberry Pi B+/2/3 & Raspberry Pi Zero.

The PiOT relay board allows you to bond a GPIO pin to a relay with the touch of a button. No need to tie pins using resistors, and no need to re-wire the circuit when you want to change which GPIO pin fires which relay. Simply select your GPIO pin using the on-board tactile buttons and two-digit 7-segment display, and switch that pin high or low to fire your designated relay!

The on-board display can be configured to show the Pi's BCM or Pin number system for GPIO/relay bonding, and also demonstrates visual feedback of the relay on/off status for easy monitoring. The display can also be used to test relays before configuring them with your Pi, in addition to providing menu access for setting configuration.

The PiOT relay board also features multiple innovative start-up modes designed to combat "chatter" on the GPIO which can lead to unexpected behavior. Variable delayed start-up allows users to pause activation of the relays for a short period during boot, ensuring that GPIO pins are correctly set prior to use, or the alternative handshake mode utilises a specific pulse train to enable activation and de-activation of the relay board at the user's will. No more accidental switching of relays at boot!

The PiOT relay board uses low current (~100mA) PWM (pulse width modulation) to significantly reduce the current required to hold the relays on when compared to other relay boards. This means that relay boards can be stacked up to 5 high without requiring additional external power.

Warning! Relays can be used to switch large voltages and currents. Please, please, please be careful when undertaking any work with this type of power - it can kill!

The ModMyPi PiOT Relay Board Features:

  • 4 x OMRON G5LA-1 Relays for Switching up to 10A @ 250VAC, or 10A @ 24VDC
  • 4 x Tactile Buttons for GPIO/Relay Bonding
  • Two-Digit 7 Segment Display for Visual Feedback & Setting Control
  • Micro-controlled GPIO/Relay Setting & Switching (No Jumpers Required!)
  • 40 Point Raspberry Pi GPIO Modelled Input
  • 5V & 3.3V Input Compatible
  • Low Holding Current via PWM ~ 100mA per Relay Board
  • Stackable Relay Board (Up to 5 Without External Power)
  • Multiple Start-Up Modes to Negate Boot GPIO Chatter (Delayed/Handshake)
  • Pi Zero Mounting Points

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!

Pi Supply Gert VGA 666 Hardware VGA for Raspberry Pi (Gert VGA)
PLEASE NOTE: SOLDERING REQUIRED - Loose componets kit form
Raspberry Pi Not Included


The Gert VGA 666 (6 bits per colour channel, hence 666) is a breakout/add on board for the Raspberry Pi Model B+,Pi 2 B and Pi 3 B (will not work with Model A/B as the additional GPIO pins are required). It is an open source hardware design recently released publicly by Gert van Loo who was one of the hardware engineers that was instrumental in the initial design of the original Raspberry Pi (also one of the chip architects on the BCM2835 chip at the heart of the Raspberry Pi) and someone that many of you may have spoken to at Raspberry Jams or on the Raspberry Pi forums. This was announced on the Raspberry Pi website and the full design files, schematics and other details are available onGitHub.

The Raspberry Pi has an HDMI port to connect a display. If your monitor only has VGA, you have to use an adapter. Because this requires a digital-to-analogue conversion, those adapters can be quite pricey, and they can draw lots of power. So our friend Gert van Loo  has created a VGA adapter that uses the Pi’s GPIO.

This wasn’t possible on the Model A or B, but now the B+ and newer models exposes 40 GPIO pins, there’s more to play with. As well as just allowing you to connect a VGA monitor natively, it also means you can use it as a secondary monitor alongside HDMI. And unlike composite video, the DPI interface can be run independent of the HDMI. The software for dual screens is still under development, but we expect that to arrive in the next couple of weeks. Running two screens at maximum resolution will consume SDRAM bandwidth, and is yet to be tested. (And there’s a catch: as the board uses most of your GPIO pins, you lose access to them.)

The VGA output supports the same resolution as your HDMI one: from 640 x 480 up to 1920 x 1024 at 60fps. At the highest resolution the pixel quality is almost as good as HDMI. The adapter uses a simple resistor ladder network as a digital-to-analogue converter, so the colour quality depends on how well-balanced your resistors are. There is slight colour banding, and with 6 bits per channel you have a maximum of 262144 colours.

Dom has been working on the software side and the new DPI (read: VGA) driver software has been added to the latest release.
