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

5V isolated motor driver module with MCU compatibility. Onboard 5V power indicator. Motor driver output voltage indication. Optional heatsink soldering. Requires only four connections from MCU: GND, 5V, PWM1, PWM2. Isolation chip powered by 5V (can share MCU 5V supply). Supports motor reversal with two PWM inputs up to 25 kHz. Error signal output for current monitoring. 5V isolation supply can be shared with MCU or sourced from onboard regulator. Operating input voltage: 5.5V–27V. Recommended input voltage range: 6V–27V. Maximum continuous current: 43A. Input logic level: 3.3V–5V. Control mode: PWM or digital level. Duty cycle range: 0–100%. Input pins: 1. RPWM – Forward PWM/level input (active high) 2. LPWM – Reverse PWM/level input (active high) 3. R_EN – Forward drive enable (high enables, low disables) 4. L_EN – Reverse drive enable (high enables, low disables) 5. R_IS – Forward current alarm output 6. L_IS – Reverse current alarm output 7. VCC – +5V power output (for MCU power connection) 8. GND – Signal ground Color: As shown in photo Material: ABS Dimensions: 5 × 5 × 3 cm Package includes: 1 × Motor Driver Module Note: Colors may vary slightly due to screen settings and lighting conditions. Dimensional tolerance: ±1–3 cm.
