BTS7960B H-bridge 43A high-power motor driver Module Overview:

This driver uses chips BTS7960 composed of high-power drive full H-bridge driver module with thermal over-current protection. Double BTS7960 H-bridge driver circuit, with a strong drive and braking, effectively isolating the microcontroller and motor driver! High-current 43A

Features:

Double BTS7960 large current (43 A) H bridge driver;

5V isolate with MCU, and effectively protect MCU;

5V power indicator on board;

voltage indication of motor driver output end;

can solder heat sink;
