This affordable, ready-assembled robotics controller board is ready to accept your micro:bit, battery power (6 to 10V) and motors of your choice to make your own DIY robot.

Use a small box, ice-cream carton or similar to house everything and you can build a really affordable robot for your school, coding club or home.

Drive:Bit uses the ever popular DRV8833 motor driver which allows you to use most small motors that operate in the 6V - 9V range.

The Drive:Bit includes a power switch, indicator LED and features a single FireLed for status indication. All the useful micro:bit pins are brought out to pads along the top of the board, with P0, P1, P2 and P8 being made available with 3-pin GVS (Ground, Voltage, Signal) headers, making it easy to connect to 3V sensors and even small micro servos

The motor and power connections can be made through the 2-pin screw terminals OR by using the 2-pin male headers behind each terminal
