The board measures 4 cm × 5 cm and has a processor, accelerometer and magnetometer sensors, Bluetooth and USB connectivity, a display consisting of 25 LEDs, two programmable buttons, and can be powered by either USB or an external battery pack. 

The list of things you can program the Microbit to do is nearly endless. You can program the buttons, LEDs and different sensors to create games and turn the Microbit into things like a pedometer, a compass or even a musical instrument.

The Prong soil moisture sensor for BBC micro:bit is a sensor board that can be directly mounted to a BBC micro:bit to monitor the moisture present in soil. The two conductive tines are placed into the soil. Any water or moisture in the soil will conduct to give an analogue voltage that can be read by the BBC micro:bit.

The Prong is powered from the 3V supply of the BBC micro:bit. Use either the USB or JST connector on the BBC micro:bit to power the circuit.

The board has been designed so that the BBC micro:bit can be bolted on using 3 x M3 nuts and 3 x M3 screws. Place the screws through the P1, 3V and GND holes of the PCB and BBC micro:bit, then use the M3 nuts to fasten together on the back of BBC micro:bit. Alternatively croc-clips can be used to connect between the Prong and the BBC micro:bit.
