The MI:power board for the micro:bit brings real portability to your wearable projects. The stylish, lightweight PCB is designed to fit snugly against the micro:bit and features a built in buzzer and 3V coin cell holder.

When assembled, the MI:power board is connected directly to the 3V, GND and P0 connections on the micro:bit. The 3V and GND connections provide power to the micro:bit and the built in buzzer is connected to P0, which is the default output pin when using the audio functions in the Block Editor software.

The board has an easy to access on/off switch, which makes it easy to turn a project on and off, rather than have to disconnect the power supply from the micro:bit.

Once the unit is assembled and attached to the micro:bit the mechanical fixings prevent the battery from being removed unless you use a screwdriver, so whatever the use, the battery will remain safely in place.

Spacers, fixings and a battery are all provided.

Please note: micro:bit is NOT included.
