DFRobot DFR0518 Micro:Mate Mini Expansion Board for micro:bit

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

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, pins 8, 12, 16 support voltage switch between 3V and 5V, allowing up to 5V, 2A digital (PWM) output.

Micro:Mate is the same size as the micro:bit. It connects to micro:bit through spring-loaded contact pins, ensuring easy, compact and secure connection. The rubber bumpers and the 3.5mm audio jack on the back keep the expansion board installed stable on the board and prevents reversed connection.

Notes:

1. The mounting screws should be well tightened to ensure a secure connection
2. Micro:Mate only supports 3V (3.3V) analog input from pins 0, 1 & 2
3. The Micro USB power port on Micro:Mate cannot be used for data transmission
4. Components with large power consumption should be connected to pin 8, 12 or 16 with 5V power supply
