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.
Botland is an official distributor of DFRobot open-source hardware. Every roboticist and practitioner of emerging technology has heard at least once of DFRobot solutions, built above all around Arduino. Our range holds original DFRobot products only.
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.
| Number | Name | Description |
|---|---|---|
1 | Audio Jack | 3.5 mm audio Jack. |
2 | Pins of I/O | The pins are compatible with the Gravity series (3 V). |
3 | External USB power port | External power supply, does not support programming. |
4 | Pins of I/O | The pins are compatible with the Gravity series (3 V and 5 V). |
5 | Switch of voltage | The switch changes the voltage between 3 V and 5 V (only for pins 8, 12, 16) and OFF. |
Key features
