product detail
Note: 5pcs 74HC244D, we prepare it for customers who need it. If you don't need it, please don't place an order. No refund will be made if the selection is wrong. Thanks for your understanding!
This driver uses chips BTN7960 composed of high-power drive full H-bridge driver module with thermal over-current protection. Double BTN7960 H-bridge driver circuit, with a strong drive and braking, effectively isolating the microcontroller and motor driver! High-current 43A
Features:
Double BTN7960 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;
Pin Definition:

Connections:
Method 1:
VCC: 5V from Microcontroller(MCU)
GND: GND from Microcontroller(MCU)
L_PWM: PWM or 5V from Microcontroller(MCU) for CCW(CW) Turns
R_PWM: PWM or 5V from Microcontroller(MCU) for CW(CCW) Turns
R_EN and L_EN: 5V from Microcontroller(MCU)
Method 2:
VCC: 5V from Microcontroller(MCU)
GND: GND from Microcontroller(MCU)
L_PWM: 5V from Microcontroller(MCU) for CCW(CW) Turns
R_PWM: 5V from Microcontroller(MCU) for CW(CCW) Turns
R_EN and L_EN: PWM from Microcontroller(MCU)
Just need four lines from MCU to driver module (GND. 5V. PWM1. PWM2);
isolation chip 5 V power supply (can share with MCU 5 V);
size: 4 * 5 * 1.2 cm;
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;
