BTS7960B module high-power motor driver H-bridge 43A PWM up to 25kHz

BTS7960B H-bridge motor driver 43A for Arduino, Raspberry Pi, ESP32, ESP8266 A high-performance DC motor control module based on a dual BTS7960 setup. It enables smooth control of motors with a maximum current draw of up to 43A. The board features a large heatsink and convenient screw terminals. The heatsink significantly improves operating stability and extends component life. Safe isolation of the control circuitry is provided by a built-in 74HC244 buffer. The module is fully compatible with popular microcontrollers such as Arduino, Raspberry Pi, ESP32, and ESP8266. It allows precise speed regulation via a PWM signal across the full range from 0% to 100%, as well as reversing rotation direction. The H-bridge design includes built-in protection against short circuits, overload, and overheating. Key technical specifications
