Revision as of 15:43, 13 July 2018

The micro:bit is a small ARMv6-M board designed for learning about computers. It can be programmed in Python, Javascript, and C/C++.

Julia Suvorova and Steffen Görtz are implementing micro:bit support in QEMU as part of the Outreachy and Google Summer of Code internship program.
