43A Dual BTS7960B H-bridge Driver Board 6-27V High-power Motor Drive PWM Module For Arduino Smart Car

Introduction (1) Product description:

This product is a high-power motor drive module. A module can only be connected to a DC motor forward and reverse. Multiple module combinations can drive multi-phase motors.

Introduction (2) Product features:

Dual BTS7960 high current (43A) H-bridge driver

5V isolation from the single-chip microcomputer, effectively protecting the single-chip microcomputer

Able to achieve positive and negative

PWM speed regulation, the highest frequency of PWM input is 25KHz

Over current, short circuit, over voltage, over heat protection

Isolate from the single-chip microcomputer to protect the single-chip microcomputer

Introduction (3) Product parameters:

Input voltage: 6-27V

Output current: maximum 43A

Input level: 3.3V-5V
