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

Regular price $14.10

In stock

Micro:Mate is a tiny BBC micro:bit I/O expansion board for learning electronics and building DIY projects.

This product requires a BBC micro:bit (available separately).

The Micro:Mate 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, 16 support voltage switching between 3V-5V, allowing up to 5V 2A digital (PWM) output.

The Micro:Mate shares same dimensions as the micro:bit. It connects to micro:bit through contact pins (with spring loaded), ensuring easy, compact and secure connection. The rubber bumpers and the 3.5mm audio jack on the back side keep the expansion installed robustly on the board, meanwhile preventing accidental reversed connection.

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 5V power supply.
