DFR0521 micro:bit Expansion Board for Boson (Gravity Compatible)

micro:bit Expansion Board for Boson (Gravity Compatible)

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 edge connector.

The expansion board comes with 6 fool-proof 3-Pin sockets, compatible with hundreds of DFRobot’s Boson and Gravitymodularized 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.

Some modules which can be used with micro:bit:

	Analog Sound Sensor DFR0034
	Joystick Module DFR0061
	Heart Rate Monitor SEN0203
