DFR0518

micro:Mate mini & thin expansion board for micro:bit (gravity compatible). It 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, pin 8, 12, 16 support voltage switch between 3V-5V, allowing up to 5V 2A digital (PWM) output. micro:Mate is in the same dimension of 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 stably on the board, meanwhile prevents reversed connection.
