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 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. NOTE: The BBC micro:bit is NOT included. https://elecena.pl/product/17394130/kitronik-mi-power-board-v2 2021-02-19 https://elecena.pl/product/17394130/kitronik-mi-power-board-v2 2022-02-22 https://elecena.pl/product/17394130/kitronik-mi-power-board-v2 2025-04-12 https://elecena.pl/product/17394130/kitronik-mi-power-board-v2 2025-07-21 https://elecena.pl/product/17394130/kitronik-mi-power-board-v2 2025-07-24 https://elecena.pl/product/17394130/kitronik-mi-power-board-v2 2025-07-26 https://elecena.pl/product/17394130/kitronik-mi-power-board-v2 2025-07-29
