This adapter board allows you to use our Raspberry Pi expansion boards with the Arduino Uno, Genuino UNO and other Arduino boards that use the same pin layout as the Uno design.

Compatible with Arduino Uno R3 and Uno R4 models.

The adapter connects the pins on the UNO to the Raspberry Pi header and has a level shifter chip to translate the voltages used by our Raspberry Pi HAT-style boards.

Solder jumpers are provided on the board, so you can set the I2C bus to connect to either Arduino pins A4 and A5 or 16 and 17.

This kit contains the following items:

  • Adapter PCB Board
  • Header pins for the Arduino / Genuino UNO
  • Header pins for the Raspberry Pi GPIO header.

Please note this kit requires a soldering iron and solder to assemble.

The Arduino header pins need to be soldered from the top of the PCB board, and the 40 pins header need to be soldered from the bottom with the header pins on the top of the PCB boards to allow you to install the Raspberry Pi expansion boards.
