Robit is a motherboard of a smart car based on micro:bit. It is compatible with MBOT. Except for the integration of the simple and convenient RJ25 connector, motor connector, and sensor on MBOT, we have extended 4 DC motor connectors, and 2 stepping motor connectors(same with 4 DC motor connectors), 8 PWM signal output connectors on this board. You can use it to drive PWM signal driving devices like a servo. It has 8 G-5V-S digital signal connectors(for connecting with OCTOPUS electric bricks). Robit can realize all the current basic functions of MBOT. Besides, you can extend its usage with more sensors, motors, servos, stepping motors, and so on.
