OverviewThe BBC micro:bit, a pocket-sized (4cm×5cm) ARM development board designed
for helping children to learn programming skills,
is now updated to the new V2 version.
You can use your BBC micro:bit for
all sorts of cool creations including digital games,
musical instruments, robots,
scientific experiments, wearable devices, and more...
The micro:bit V2 adopts faster ARM Cortex-M4 nRF52833 processor,
integrates 2.4G Radio/BLE Bluetooth 5.0, and now includes built-in MEMS microphone,
speaker, and touch sensitive logo pin,
