Description
The Xia Mi expansion board adds more than 10 functional modules and expansion features for your BBC micro:bit V2 including multiple sensors, a 4-way motor driver, RGB LEDs, OLED display, relay, IR receiver and more!
This awesome buffet of features allows budding coders to learn both the basic functions of the micro:bit with the option to progress using the many onboard features and online tutorials. It's a quick, simple and hassle-free way to explore different hardware whilst learning to code.
The board makes a great foundation for micro:bit robotics projects too, with the onboard motor driver and distance sensor ports allowing easy expansion.
