High Power 43A Motor Driver Module for Arduino with Current Limit Function

5V isolated interface with MCU for effective protection; onboard 5V power indicator. Voltage indication at motor driver output; heatsink soldering supported. Requires only four connections from MCU to driver module: GND, 5V, PWM1, PWM2. Isolation chip powered by 5V (can share supply with MCU). Supports bidirectional motor control; two PWM inputs with frequency up to 25 kHz. Two current-sensing outputs for fault detection. 5V supply for isolation chip can be shared with MCU or sourced from onboard regulator; operating input voltage range: 5.5V–27V. Input voltage range: 6V–27V Maximum continuous current: 43A Input logic level: 3.3V–5V Control method: PWM or digital level Duty cycle range: 0–100% Input pins: 1. RPWM: Forward direction PWM or level signal input (active high) 2. LPWM: Reverse direction PWM or level signal input (active high) 3. R_EN: Forward drive enable input (high enables, low disables) 4. L_EN: Reverse drive enable input (high enables, low disables) 5. R_IS: Forward current sense alarm output 6. L_IS: Reverse current sense alarm output 7. VCC: +5V power output (for MCU power connection) 8. GND: Signal ground reference Color: As shown in photo Material: ABS Dimensions: 5 × 5 × 3 cm Package includes: 1 × Motor Driver Module Note: Color may vary slightly due to lighting and display differences. Dimensional tolerance: ±1–3 cm.
