This is a micro:bit V2-based multi-functional expansion board for programming education. Featuring a small size of 57*87mm and a compact layout, the board expands more than 10 functional modules including sensors of all kinds, 4-way motor, LED lights, OLED screen, and external power supply, which allows students to not only learn the basic functions of micro:bit but also further advance to the next level like controlling robot cars, Mecanum wheel robot, and so on. Moreover, even with so many things integrated on the board, the price still remains low. Come and explore all these extra features!

Note: Xia mi Multi-functional Expansion Board only compatible with micro:bit V2, not compatible with micro:bit V1 board.
