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!

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. Higher resolution will slow down your Pi and use more RAM.

Features:

- 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

Note:

Raspberry Pi main board is not included.

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.

Dimensions: 0.63 x 0.52" (16.05 x 13.33mm)

OnOff SHIM (3A4 On/Off Shim)

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.

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 capability, a 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.

Unicorn HAT (3B4 Unicorn HAT)

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!

Best of all, Adafruit even have a Python library you can use, so you'll be up and running instantly, to make your robotic creation com to life. The Adafruit PWM/Servo HAT is the perfect solution for any project that requires a lot of servos or PWM outputs! Check out Adafruits detailed tutorial for lots more information including diagrams, schematics, installation instructions and more

Each order contains

  • a Servo HAT
  • a 2-pin terminal block
  • four 3x4 headers
  • a 2x20 socket header

You'll need to do some light through-hole soldering to attach the headers onto the HAT circuit board. If you would like to stack multiple HATs onto one Pi, you can also pick up a 2x20 stacking header and a set of right-angle 3x4 headers that should be soldered on instead.

Please note! This kit does not come with Raspberry Pi, servos, or required 5V power supply.
