miniROS Robot Controller STM32 Chip 6-14V Voltage Support Encoder Motor Bus Servo Independent Power Supply System

The miniROS Robot Controller is an integrated, high-performance control board powered by an STM32 chip, designed specifically for building advanced ROS-based robotic vehicles and arms. It is an ideal choice for South African students, educators, and hobbyists looking to develop complex drive configurations and articulated robotics. The board simplifies development by combining motor drivers, sensor interfaces, and robust power management onto a single platform.

High-performance STM32 main control chip

Built on a Cortex-M4 core running at 168MHz, the onboard STM32F407VET6 chip features an integrated FPU and a Murata crystal oscillator. This ensures high-speed processing and stable performance for demanding robotics algorithms.

Onboard six-axis IMU pose sensor

The integrated MPU6050 sensor provides real-time posture data, featuring a three-axis accelerometer and a three-axis gyroscope. Developers can easily initialize registers and print raw six-axis IMU data for precise navigation.

Four-channel encoder motor driver

The controller supports up to four encoder motors with PID speed control, making it compatible with diverse chassis designs. It easily drives mecanum, omnidirectional, Ackermann, steering, and differential drive configurations.

Serial bus servo expansion

Dedicated serial bus servo ports allow you to expand your build with a 6DOF robotic arm or other articulated robotic joints. A single USB connection can be used to control and read data from both the motors and connected servos.

Independent power supply system

Featuring a dedicated power switch, two power inputs, and five power output channels, this system provides stable power for expansion. The board supports an input voltage range of 6-14V to suit various battery setups.

Industrial-grade circuit protection

To prevent accidental damage during prototyping, the board is equipped with comprehensive safeguards. These include protection against reverse connection, overcurrent, overheating, and backflow.

Multi-platform ROS controller compatibility

The board seamlessly interfaces with popular ROS master controllers, including Raspberry Pi, Jetson, Sunrise Pi, and industrial computers. It also features an onboard PS2 receiver port for direct remote control up to a range of 10 metres.
