ROS robot driver board (including schematic diagram and PCB) has been tested and is in use

ROS robot driver board, balance car driver board, high-power motor driver board, ROS robot driver board, ROS robot control board, motor driver board have been drawn . The board is designed for high-power ros trolleys, and can also be used for balance cars and more The use of a smart car leads to four motor encoder integrated interfaces, reducing cumbersome wiring, using stm32f103zet6 as the controller, 144 pins, and sufficient hardware resources. The motor driver uses the btn7971B chip, which is large enough to load Human, can drive 24V motor, can drive high current motor, wide range power input 6V-35V, dual LM25965.0 chip, 5V-3A dual USB port from the board to easily power Raspberry Pi or nanopi, in addition to Multiple serial ports, iic interface, easy to add peripherals and debugging, encoder and motor interface integration saves wiring troubles, leads to oled interface and gy-85 gyroscope interface, leads to MINIUSB and MICORUSB two interfaces, two interfaces All with a serial port circuit, support serial port download. High cost performance, the pin definition is the same as that of the rikirobot (1300 on the same board of Riki), and it is fully compatible with the underlying driver code after my test. I can provide some technical or hardware guidance.
In addition, there are boards or empty boards of existing cars for sale, as well as well-tuned ROS cars. If you need it, you can leave a message and reply as soon as possible.
