## Description

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. This latest version has been redesigned to fit both the the V1 and V2 micro:bit.

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](https://core-electronics.com.au/micro-bit-v2-australia.html) is NOT included. Battery is included.*
