micro: IoT - micro:bit IoT Expansion Board
We have ✅ 5 available of the DF-MBT0012 in our Sydney warehouse. An extra 68 units available with a short lead time.
The micro:IoT is a feature-packed IoT expansion board for the BBC micro:bit. It integrates Wi-Fi connectivity, an OLED display, motor drivers, servo outputs, and a range of I/O ports into a compact cloud-shaped PCB — everything needed to build IoT projects with minimal setup.
Designed to work with the DFRobot Easy IoT platform, the board lowers the barrier to building connected projects. It supports MakeCode, Mind+, and Python programming environments. A PMMA protective case shields the onboard components.
