Note: This product has been redesigned to work for all versions of the BBC micro:bit and is available to buy here.
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.
Features:
- Power your BBC micro:bit from a stylish PCB.
- On-Board buzzer.
- Easy access on/off switch.

Unlike the others, I recognize that when you work with kids you want them to NOT be able to easily access the button battery. This button cell battery pack for the microbit is the one I recommend for teachers to buy specifically because the battery is difficult to access. Given that kids are really the target market for the Microbit I’m glad you thought through the safety aspect of designing it this way.

Yes it is very helpful, but i can not change the Battery. If you change the GPIO, than we can rotate it and fix!
I hope you make a second version

This is a nice little battery kit that makes the micro:bit very mobile and compact. My only problem is you can’t replace the battery without disassembling it. It would be nice if you could pop the old battery out and a new one in without unscrewing the bolts.
