Important Installation Notes
- Verify motor voltage and power parameters do not exceed specified ranges
- For motors below 100W, no heatsink required with normal ventilation
- Use shielded wires when distance between driver and motor exceeds 50cm
- Control port spacing: 2.54mm, Power port spacing: 3.96mm
- Ensure proper insulation between driver MOSFET and heatsink/installation plate
- 5V output port is for control signals only - do not connect external power equipment
