Product Description

DF Robot Boson Expansion Board for the BBC micro:bit

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, DF Robot has 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 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.
