5V isolated motor driver module with MCU compatibility. On-board 5V power indicator. Voltage indication for motor driver output. Optional heat sink soldering. Requires only four connections from MCU: GND, 5V, PWM1, PWM2. Isolation chip powered by 5V (can share MCU 5V supply). Supports bidirectional motor control with two PWM inputs up to 25 kHz. Dual current-sense error signal outputs. 5V isolation supply can be shared with MCU or sourced from on-board regulator. Operating input voltage range: 5.5V–27V. Recommended input voltage: 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 or level signal input (active high) 2. LPWM: Reverse 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: Colors may vary slightly due to lighting and display differences. Dimensional tolerance: ±1–3 cm.
