PWM1. PWM2); isolation chip 5V power supply (can share with MCU 5V); Able to reverse the motor forward, two PWM input frequency up to 25kHZ; two heat flow passing through an error signal output; isolated chip 5V power supply (can be shared with the MCU 5V), can also use the on-board 5V supply; the supply voltage 5.5V to 27V; Package include: 1pcs BTS7960 motor driver module

5V isolated with the microcontroller, effectively protecting the microcontroller. BTS7960 able to reverse the motor forward, two PWM input frequency up to 25kHZ. BTS7960 large current (43 A) H bridge driver, 5V power indicator on board; 5V isolate with MCU, and effectively protect MCU. Voltage indication of motor driver output end,can solder heat sink. This driver uses chips BTS7960 composed of high-power drive full H-bridge driver module with thermal over-current protection.
