47 In stock

BitWear is a low-cost compact accessory for micro:bit users to make fun wearable gadgets, sew it onto your outfit or use a strap to make your own smartwatch or wearable metronome.

BitWear is a low-cost compact accessory for micro:bit users to make fun wearable gadgets.

There is a vibration motor, a buzzer and an addressable RGB LED on board, all designed for your fun wearable projects.The board also allows you to turn off the motor and pixels with switches so you can use the touch pins or the breakout holes for other uses.

The BitWear is simply attached to the micro:bit with 5 screws (M3x5mm),and powered with two CR2032 batteries, which are securely clipped in and unable to be taken out unless you unscrew the BitWear.

Our goal design for the BitWear is to maximise micro:bit functions while minimising the space footprint to provide new micro:bit users with a enriched wearble experience. Our BitWearable Kit comes with a handy strap so for all your strapping projects, we suggest you consider the BitWearable Kit.
