Board Introduction: ROS robot control board uses the high-performance STM32F407VET6 main control chip, and has built-in important IMU attitude sensor and other key configurations. In addition, the control board also provides four-way encoder motor interface, PWM/bus servo interface, LCD color screen display and USB/SBUS/CAN/Bluetooth and other communication peripheral interfaces. Only one USB cable is needed to control and read encoder motors, various servos and peripherals. It is simple and efficient!
