micro:bit is a pocket-sized microcontroller designed for kids and beginners to learn coding and electronics, letting them easily bring ideas into DIY digital games, interactive projects, and robotics.
However, on-board I/O rings and crocodile clips sometimes are not handy and safe enough to connect peripherals. To explore more possibilities with micro:bit, we have designed the micro:bit Expansion Board for Boson, a carry-on board that connects to micro:bit via the edge connector.
The expansion board comes with 6 fool-proof 3-Pin sockets, compatible with hundreds of DFRobot’s Boson and Gravity modularized electronic blocks, covering most popular digital and analog sensors and actuators, supporting sound, light, and motion interaction.

Moreover, the expansion board adds a Gravity: HuskyLens interface and an IIC interface. To ensure a steady current supply for these peripherals, the expansion board can be powered externally through the Micro-USB power port.
