The MI:power board for the BBC micro:bit brings real portability to your wearable projects. The stylish, lightweight PCB is designed to fit snugly against the BBC 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 BBC micro:bit.

Once the unit is assembled and attached to the BBC 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: BBC micro:bit is NOT included.

MI:power board for the BBC micro:bit

A simple and compact way of adding the sound functionality to the micro:bit

T
Toni Falusi
Compact souce of power and adds music capablity

Pros: Students love adding sound to their micro:bit projects and this board allows for that, along with the elimination of the bulky external battery pack.
Cons: Shields cannot be added to the micro:bit and changing the battery requires the screws to be removed from the board. If the battery holder was up the other way, the battery could be pushed out and replaced without requiring disassembly.
Still love it and recommend the board for primary school classrooms

MI:power board for the BBC micro:bit

Love them, they are so much easier to use than the plug in battery packs. They bolt on to the MicroBit board.
