The Raspberry Pi Sense HAT is attached on top of the Raspberry Pi via the 40 GPIO pins. The Sense HAT has an integrated Gyroscope, Accelerometer, Magnetometer, Barometer, Temperature Sensor, Humidity Sensor, 5-button joystick and 8×8 LED matrix display that can be used for many different types of experiments, applications, and even games.
The PiFace Digital 2 add-on board for Raspberry Pi Model B+ connects to the Pi to the world around it. The PiFace Digital 2 includes 2 relays, 4 tactile switches, 8 digital inputs, 8 LED Indicators, a graphical emulator and support for hardware interrupts.
The PiFace Control and Display has been updated for the Raspberry Pi Model B+! It has a 16 character, two line display (16×2), 5 push-button tactile switches, a LED backlight, a 3-position navigation switch, and an IR Receiver. It comes with Python Libraries so you can control it, and has immediate uses in Internet Radio, Streaming media and embedded Applications.
The PIFACE IO Shim works with the Raspberry Pi 2 and Raspberry Pi B+ with 40 GPIOs to duplicate the header pins when an add-on board is connected directly to the Raspberry Pi GPIO. The SHIM has two sets of plated thru holes in the same RPI GPIO configuration with the relative holes connected together. With one set of holes placed over the Raspberry Pi headers the other set of holes on the SHIM can accommodate header pins, wires, etc. to support the users application while not covering up the RPI header pins for additional add on boards.
Give your Pi some reach with this GPIO extender cable, which has two matching connectors on the end of a 12″ (300mm) long gray cable. Plug one end into your Pi and the other end will have a boxed male header you can plug in a Pi Plate that is expecting to go onto a Pi. This cable is not compatible with the Raspberry Pi Model B+.
The Sound Sensor is a microphone that allows your GrovePi or GoPiGo robot car to listen to sound strength, so you can control it to take a picture or move around based on changes in noise! Cable included.
At the highest level, FPGAs are reprogrammable silicon chips. Using prebuilt logic blocks and programmable routing resources, you can configure these chips to implement custom hardware functionality without ever having to pick up a breadboard or soldering iron. FPGAs have gone from being simple glue logic chips to actually replacing custom application-specific integrated circuits (ASICs) and processors for signal processing and control applications. The LOGi-Pi is a FPGA platform for your Raspberry Pi. The LOGi Ecosystem of FPGA hardware, software, drivers and applications mitigates the sharp learning curve associated with FPGA development while unifying existing hardware interfaces and platforms. FPGA (Field Programmable Gate Array) development is an invaluable technology that allows a single board/device to morph in functionality to fit the needs of changing environments and application requirements.
The MICROSTACK ACCELEROMETER provides easy, plug and play integration and development for designs requiring a accelerometer function to all platforms compatible with the Microstack framework. The Acceleration sensor features a MMA8491Q is a low voltage, 3-axis low-g accelerometer in a 3x3mm QFN package that can accommodate two configurations, acting as either a 45° tilt sensor or a digital output 14-bit ±8g accelerometer with I2C bus, and connects to the MicroStack Baseboard.
The Condor Raspberry Pi USB to 2 Port USB Powered Hub + 2 Ports UART Board mounts on top of the Raspberry Pi and provides 2x USB Ports and 2x UART ports. It connects to the Raspberry Pi with a micro-USB Cable (not supplied)
