ELECFreaks 電源：ビット、マイクロ：ビット用

These are nice well-made little options to power my micro:bit. Glad they also added a speaker. Quite happy with my purchase of three of these, both for my own use and my grand niece. Would have given bit higher rating but minor inconvenience to require removing it to allow plugging into my other expansion card sockets.

Add on accessory to the micro:bit works great for limited space applications and includes a buzzer. Works well with 2032 button cells but can just squeeze in the 2050’s!
