5V isolated power supply with MCU protection; onboard 5V power indicator; motor driver output voltage indication; compatible with soldered heat sink. Requires only four connections from MCU to driver module (GND, 5V, PWM1, PWM2). Isolation chip powered by 5V (can share MCU 5V supply). Supports bidirectional motor control; two PWM inputs with frequency 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. Input voltage range: 6V–27V Maximum continuous current: 43A Input logic level: 3.3V–5V Control method: PWM or logic level Duty cycle range: 0–100% Input/Output pins: 1. RPWM: Forward direction PWM or logic level input (active high) 2. LPWM: Reverse direction PWM or logic level 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 appearance may vary slightly due to lighting and display settings. Dimensional tolerance: ±1–3 cm.
