micro:Mate - Mini Expansion Board for micro:bit (Gravity Compatible)

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.

Note: micro:bit board is NOT included

* The mounting screws should be well tightened to ensure a secured connection

* micro:Mate only supports 3V (3.3V) analog input from Pin 0, 1, 2

* The Micro USB Power port on Micro:Mate cannot be used for data transmission

* Components with large power consumption should be connected to Pin 8, 12, 16 with a 5V power supply
