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.

ModMyPi Serial HAT (RS232) (2C4 MMP Serial HAT)

RASPBERRY PI NOT INCLUDED


The Serial HAT from ModMyPi features a Male DB9 RS232 port connected to the Pi's UART pins via a MAX3232 IC. The MAX3232 IC converts the Pi's UART port to RS232, which enables serial communication with any RS232 compatible serial device!

RS232 is a legacy serial communication standard used in millions of devices globally including: printers, modems, data terminals, interface devices (keyboards/joysticks/mice), medical equipment, servers, instrumentation, industrial control equipment (PLC's, CNC, embedded computers), microcontroller development kits, service access points, sensor interfaces and many more! Many are being superseded by USB or even Bluetooth Low Energy but RS232 is still used in a lot of places and on loads of legacy equipment!

You can connect to the RS232 port on the Serial HAT via the male DB9 port (through use of a serial/null-modem cable) or via the TX/RX/GND solder points on the Serial HAT PCB. The Serial HAT can also be used for remote terminal access to your Raspberry Pi using a computer. You'll need a Female to Female Null Modem Cable, and a Serial to USB cable to achieve this!

ModMyPi PiOT Relay Board (2A3 MMP PiOT relay board)

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

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!

Nanomesher - Hackable Raspberry Pi Switch w/ Remote Control (3A5 Nanomesher power switch)

This neat little board from Nanomesher adds a programmable power switch to your Raspberry Pi A+/B+/2/3/Zero/Zero W, which can be controlled by a single button or IR remote!

This is the Hackable Raspberry Pi Power switch which was successfully funded on Kickstarter in April 2017.

The Hackable Raspberry Pi Switch features an on board and removable Attiny85 Arduino Development MCU, which means the switch is both Smart and Hackable!

The Pi Switch Features

  • Single button on/off or Infrared (IR) remote operation (Remote Included)
  • LED light to indicate power status
  • Blinks twice when Switch receives power
  • Turn On when Pi is on
  • Blinks when waiting for Pi to turn off
  • Turn Off when Pi is off
  • Use standard microUSB and USB female socket
  • Suitable for mounting on front face plate
  • Onboard Attiny85 Microprocessor can be removed and reprogrammed if needed

Package Include:

  • Hackable and Smart Pi Power Switch with removable Attiny85 microcontroller
  • 4 x Jumper cables to Pi
  • High Quality MicroUSB cable (20cm)
  • Infrared remote control

While it works out of the box. You can also reprogram it using an Attiny MCU programmer. Code and Guides are included are downloadable from here. There is a package which include both the Switch and Programmer

Being Hackable, the firmware can be modified so that the switch can be used as a development board with these functions:

  • One output to trigger relay
  • One output to LED
  • One analog input to detect voltage between 0-5v
  • One input for push button
  • One input for infrared receiver which I have the code to distinguish all the buttons in the remote included
  • One output to trigger an external digital input (pull down)

Operation Sequence

1. Press once to turn On

2. Press again to trigger shutdown of the Pi's Linus OS using the shutdown script

3.  Switch will monitor the Pi and wait for the Pi to be fully shutdown (halt state)

4. Once halt state is detected, cut the power to the Pi.
