Tips

For best performance, ensure adequate airflow around the module if operating near maximum load. The through-hole pins allow secure soldering; consider using a heat sink on the PCB copper area if ambient temperatures exceed 50°C. Always verify that your load current does not exceed 1A to avoid triggering the overload protection.
