This is the official, micro:bit-branded, AAA battery pack with a handy ON/OFF switch. This battery pack allows you to power your micro:bit projects without a USB cable, using the battery socket on your micro:bit board - great for those projects that require movement, motion and more! The battery pack fits 2x AAA batteries (not included) under the easy-to-remove slide-off micro:bit-branded cover. We also stock an option without an ON/OFF switch, which might be more suitable depending on your project and environment.
