micro:Mate is a tiny micro:bit I/O expansion board for learning electronics and building DIY projects. It expands 6 sets of 3-pin I/O interfaces, capable of connecting DFRobot Gravity series modules, servo motors, sensors and jumper wires.

Additionally, Pin 8, 12 and 16 support voltage switch between 3V-5V, allowing up to 5V 2A digital (PWM) output!

Micro:Mate is the same dimensions as the BBC micro:bit board. It connects to the micro:bit through spring-loaded contact pins ensuring an easy, compact and secure connection. The rubber bumpers and the 3.5mm audio jack on the back side ensure a stable connection and prevent reversed connections.
