micro:Mate - I/O expansion board for micro:bit

Micro:Mate is a tiny micro:bit I/O expansion board for learning electronics and DIY projects. It expands micro:bit to 6 sets of 3-pin I/O interfaces for DFRobot Gravity modules, servos, sensors and jumper wires. Pins 8,12,16 support 3V-5V switch, allowing 5V 2A digital (PWM) output. Same size as micro:bit, it connects via spring-loaded pins for easy, compact, secure connection. Rubber bumpers and a 3.5mm audio jack on the back ensure stable installation without reversed connection.
