The neo:bit is an add-on board for connecting NeoPixels to a BBC micro:bit. It gives you:

• A level shifter connected to pin P0 for driving NeoPixels.
• Two slide potentiometers, connected to pins P1 and P2.
• A barrel connector for a 5V power supply, which powers the NeoPixels, and can also power the micro:bit via a 3.3V regulator.

Test board for wiringPi Haskell binding, v1.2

This is a simple add-on board for Raspberry Pi. It is meant for testing the Haskell binding for wiringPi. It connects to the Raspberry Pi via a 40-pin ribbon cable, and has the following features:

• wiringPi pins 0-7 are connected to yellow LEDs

• wiringPi pins 26 and 23 are connected to red LEDs

• wiringPi pins 21 and 22 are connected to each other (via a resistor to prevent short circuits) to allow for automated testing (i. e. an output pin sending to an input pin)

• wiringPi pin 25 is connected to a momentary pushbutton which pulls it to ground via a resistor (so pin should be configured with an internal pullup)

See GitHub for more information and BOM.
