A small robot has many joint actions and each joint is a control motor.

Based on MindMotion’s MM32SPIN222C microcontroller, the motor control scheme takes MM32SPIN222C as the main control:

- Highly integrated solution with MOSFET and LDO integrated in the chip

- Overvoltage and overcurrent protection

- Position speed control

- Single UART communication

MM32 MCU Model:

MM32SPIN222C Series
