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 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 on-board 3.5MM headphone jack and volume knob supports direct connection of headphone. 
To ensure a steady current supply for these peripherals, the expansion board can be powered externally through the USB power port.
