Provides 5V isolation with an MCU, effectively protecting it. Features a 5V indicator on the board. Displays voltage indication of the motor driver output; heatsinks can be soldered. Requires only four lines from the MCU to the drive module (GND, 5V, PWM1, PWM2). Features isolated chip 5V supply (can be shared with MCU 5V). Capable of reversing the motor forward, with two PWM input frequencies up to 25kHz. Includes two heat flows passing through a fault signal output. Isolated chip 5V supply (can be shared with MCU 5V), or can use the built-in 5V supply. Supply voltage range: 55V to 27V. Input Voltage: 6V-27V. Maximum Current: 43A. Input Level: 3.3-5V. Control: PWM or Level. Duty Cycle: 0-100%. Input Port: 1RPWM: Forward level or PWM signal input, active high. 2LPWM: Reverse level or PWM signal input, active high. 3R_EN: Forward drive enable input, high level enable, low level disable. 4L_EN: Reverse drive enable input, high level enable, low level disable. 5R_IS: Forward drive current alarm output. 6L_IS: Reverse drive current alarm output. 7VCC: +5V output, 5V supply connection with microcontroller. 8GND: Signal common low end. Color: Photo Color. Material: ABS. Size: 5 x 5 x 3cm. Package Contents: 1 x Motor Driver Module. Other products are not included. Note: Light and different displays may cause the color of the item in the picture to be slightly different from the real one. The allowed measurement error is +/- 1-3cm.
