Elecfreaks mBot Robot Board for the BBC micro:bit

Convert your mBot V1.1 from Arduino to a micro:bit controller with the Elecfreaks mBot Robot Board, a control board for a smart car based on the BBC micro:bit that is compatible with the mBot.

Except for the integration of the simple and convinient RJ25 connector´╝îmotor connector and sensor, this mBot Robot control board has added 4 DC motor connectors, 2 stepping motor connectors(same with 4 DC motor connectors) and 8 PWM signal output connectors.

You can use it to drive PWM signal driving devices like servos with the 8 G-5V-S digital signal connectors(for connecting with OCTOPUS electric bricks). The mBot Robot Board can realize all current basic functions of the mBot.


  • Compatible with MBOT chassis and sensors
  • Support 4 channels of DC motors and 2 channels of stepping motors
  • 8 PWM signal output connectors
  • 8 G-5V-S digital signal connectors(for OCTOPUS electric brick)
  • 4 G-5V-S analog signal connectors(for OCTOPUS electric brick)
  • Integrate frequently used modules like buzzer's, rainbow LED's, light sensor's, infrared send and receive

Pins & Connectors
