  • micro:bit GPIO Expansion Board WITHOUT micro:bit board.


GPIO Expansion Board + micro:bit V2 SingleGPIO Expansion Board ONLY (without micro:bit)




Note: This GPIO Expansion board works with both micro:bit V1 and micro:bit V2.


This is a low-cost expansion board for micro:bit, which is specifically used for the IO ports of micro:bit. It has expanded all the IO pins on the micro:bit, and also comes with a built-in buzzer. The small size is very suitable for small projects using micro:bit.



The buzzer is connected to the P0 pin. If you remove this jumper cap, it disconnects the connection between the buzzer and P0 pin. The buzzer will not make any sound while you can use P0 pin like other normal IO pin.

At the back of this microbit GPIO Expansion Board, all the pins are labeled with the name and feature it holds like MOSI, MISO, Button A, and Button B so there is no need for you to check on the pinout via Google Image :)

Note: DO NOT place it on a metal surface to avoid a short circuit.
Warranty Period: 12 months
  • Works with both the micro:bit V1 and micro:bit V2
