Overview

This ROS robot control board is based on the STM32F407VET6 (Cortex-M4, 168MHz) and integrates an MPU6050 IMU (6-axis pose sensor). It provides motor/servo control interfaces plus USB communication peripherals, supporting ROS expansion and controller switching for platforms such as Raspberry Pi and NVIDIA Jetson series controllers. ROS1 and ROS2 SDKs (Python 3) and ROS chassis source code are provided, covering motor control, attitude calculation, and PC communication.

Key Features

  • STM32F407VET6 main control: Cortex-M4 core, 168MHz main frequency, built-in FPU, Murata crystal oscillator.
  • 4-channel encoder motor drive: supports up to 4 encoder motors with PID speed control.
  • Servo expansion: 4-channel PWM servo port (5V drive) and 2 serial bus servo ports (drive voltage equals power supply voltage).
  • Multiple control/IO interfaces: USB, SBUS, I2C expansion, Bluetooth (UART), USB HOST, UART and GPIO expansion.
  • Line follower support: dedicated I2C port supports connection to 4-channel line follower and 6-channel photoelectric line follower.
  • Protection circuits: reverse connection, overcurrent, overheating, backflow protection; also overheat, short-circuit, and over-current protection.
  • Power options: DC 7-14V input; Type-C external power supply port (independent 5V5A) for powering devices such as Raspberry Pi and Jetson Nano.
