STM32F407 main control, Cortex-M4 core, 168MHz main frequency, built-in FPU, Murata crystal oscillator, high speed, high performance, high stability.

Onboard 6-axis IMU posture sensor MPU6050, allowing IMU register initialization and printing raw six-axis IMU data, including 3-axis accelerometer and 3-axis gyroscope readings.

The on-board serial bus servo port enables the expansion of the 6DOF robot arm and other articulated robots.

Compatible with Raspberry Pi, JETSON, industrial computers, Sunrise Pi, and other ROS master controllers.

The controller can drive 4-channel encoder motors with PID speed control. It meets the diverse requirements of various types of vehicles available on the market, including two-wheel drive, four-wheel drive differential, mecanum-wheel, omnidirectional-wheel, steering, and Ackermann cars.

Featuring industrial-grade circuit protection, this system is equipped with a comprehensive power protection mechanism, including safeguards against reverse connection, overcurrent, overheating, and backflow, effectively minimizing the risk of burnout during operation.

The mini ROS robot's independent power supply system includes a dedicated power switch and features two power input ports and a 5-channel power output port, providing stable power for robot development and expansion.

The controller features an onboard PS2 controller receiver port, allowing connection to a PS2 controller. You can directly connect the controller receiver to the controller, enabling remote control within a range of 10 meters.
