STM32F103RCT6 Control Board with MPU9250 9 Axis Sensor PID Closed-Loop Motor Drive for ROS ROS2 Robot The ROS robot control board is both a ROS robot car drive controller and an STM32 core development board. The board integrates important configurations such as the STM32 core control unit and the nine-axis IMU attitude sensor, and also provides peripheral interfaces such as four-way encoder motors, four-way PWM servos, serial bus servos, and RGB light strips. It supports the for 5 power supply protocol, and supports ROS master communication and power supply for , , industrial computers, Horizon RDK, etc. ROS developers do not need to write peripheral drivers themselves, they only need to send corresponding control commands to this product through the serial port to quickly control the peripherals, which is simple and efficient.
