Octopus 5-button ADKeypad

Octopus ADKeypad Brick uses an analog input to read the five key state which saves IO resource for the Arduino. It can be used together with an I/O expansion boards to make amazing interactive project.

All five buttons are read through a single analog pin: each button gives a different analog value, so your program can tell which one was pressed. It works with the micro:bit at 3V and has a 3-pin plug-and-play connector.
