Keyestudio PRO MICRO Development Board


Micro: bit is an ARM-based microcontroller designed by BBC. Consisting of onboard Bluetooth, accelerometer, electronic compass, three buttons, 5 x 5 LED dot matrix, it is only half the size of credit card and mainly used for programming education for teenagers. In order to carry it conveniently, we put a micro: bit control board and two manuals in storage bag. The storage bag is light and beautiful.
