Description
Micro:mate is a small expansion board of I/O for micro:bit for learning the electronics and building the projects. Board has 6 rows of 3-pin interfaces of I/O, thanks to which you can connect the modules from the Gravity series, servos, sensors and wires. Pins - 8, 12, 16 - support the voltage from 3 V to 5 V what allows for the digital output (PWM) up to 5 V / 2 A.
Micro:Mate has the same dimensions as micro:bit. The board is connected with micro:bit through the contacts, providing an easy, concrete and safe connection. Rubber covers and 3.5 mm audio jack at its bottom, provide a stable installation of the expander on the board micro:bit.
Pins
The board has 6 rows of 3-pin I/O interfaces, pins 8, 12, 16 support voltage from 3 V to 5 V. Board is powered with the voltage from 3.3 V to 5 V.

Key features
- Colored 3-pin interfaces compatible with hundreds of electronic modules of plug&play
- 3 analog inputs, 6 digital inputs/outputs (PWM), switch of 3 V / 5 V, connector of 3.5 mm audio jack
- External USB power port, up to 5 V / 2 A
Notes
- The mounting screws should be well tightened to ensure reliable connection
- Micro:Mate only supports the voltage of 3 V (3.3 V) of the analog output from pins 0, 1, 2
- The microUSB port cannot be used for data transmission
- Modules with a higher demand for electricity, should be connected to pins 8, 12, 16 with a voltage of 5 V
