Introducon: The Mi-Power board provides a lightweight, slim prole soluon

to powering and adding sound to your BBC micro:bit. The board connects

directly to the BBC micro:bit using the included screws, spacers and nuts.

Examples of board in use: Doing away with bulky AAA baeries provides

many new and excing possibilies for your BBC micro:bit. How about a BBC

micro:bit belt buckle or watch? The low prole MI-power board assembly

makes adding the BBC micro:bit to your wearable projects that much easier.

of 200mAh which depending on use should last up to 20 hours. The on-board
