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. **Includes:** * 1x MI:power board for the BBC micro:bit. * 3x Counter Sunk M3 Machine Screws. * 3x M3 Hex Full Width Nuts. * 3x Plastic Spacers. * 1x CR2032 3V Coin Cell. **Features:** * Dimensions: - Length: 51mm. - Width: 42mm. - Height: 6mm. * Power your BBC micro:bit from a stylish PCB. * Break free from the tether to the computer and take your project mobile. * On-Board buzzer. * Easy access on/off switch. * Great for micro:bit mood badges, to allow your micro:bit to become a handheld remote control, and much more. * This accessory is supplied with spacers, fixings and a battery. * No soldering required. **Documents:** * [Assembly Guide](https://cdn.sparkfun.com/assets/b/b/0/d/9/17852-Kitronik_MI_power_Board_V2-Assembly_Guide.pdf) **Videos**
