Product Introduction:
This product is a high-power motor drive module. One module can only connect the motor forward and reverse. Multiple modules can drive multi-phase motors.
Dual BTS7960 high current (43A) H-bridge driver
Isolated from 5V of MCU, effectively protects MCU
Can realize forward and reverse rotation
PWM speed regulation, PWM input maximum frequency 25KHZ
Overcurrent, short circuit, overvoltage, overheat protection
Isolated from MCU, protects MCU

Wiring diagram
If you use the module to drive the DC motor, you can refer to the above diagram for wiring. As for the single-chip program, you can write it yourself. If you are using the Arduino development board, it will be very simple. Arduino provides development libraries and sample programs for this driver board. The current alarm pin is not connected in the figure. You need to check the BTS7960 data sheet. The data sheet contains instructions for the use of this pin.
Precautions:
1. Pay attention to the wiring diagram and do not make a mistake.
2. This document only represents the product knowledge and parameters at the time of editing. If you have purchase needs, you can contact this store to inquire about the latest situation.Thanks.
