micro:IO IO Expansion Board for BBC micro:bit

This DFRobot IO expansion board for the BBC micro:bit breaks out the IO pins to 3-pin headers with signal, 3V3 and GND, matching the DFRobot Gravity interface. A buzzer on P0 can be switched off with a slide switch. The labelling on the board shows the function of each interface.

Note: DFRobot now supplies version V2.0 with its own 5 V Micro USB connector and switch, a 5 V I2C port for the HuskyLens AI camera and two 3.3 V I2C ports. Version V2.0 no longer has the ring contacts for crocodile clips. When the HuskyLens is connected, power the board via Micro USB.
