1. Disconnect the power supply before connecting the module.
2. Identify the input and output terminals using the markings on the actual circuit board.
3. Connect a compatible DC input supply with the correct polarity.
4. Before attaching sensitive electronics, measure the output with a multimeter.
5. Adjust the onboard potentiometer until the required output voltage is reached.
6. Confirm that the voltage and current requirements of the connected device are within the module\'s supported limits.
7. Check the output again after connecting the load.

Important: This is a step-down converter, not a voltage booster. It cannot produce an output voltage higher than its input. Adequate voltage headroom is required for proper regulation.

Power supply, multimeter, wiring, enclosure, and other demonstration accessories are not included unless specifically stated in the listing.

Important Notes & Safety Information

• Use with compatible DC power supplies only.
• Check input/output polarity carefully before applying power.
• Measure and adjust the output voltage before connecting sensitive equipment.
• The achievable output voltage depends on the supplied input voltage and operating conditions.
• Do not exceed the module\'s verified current, thermal, or voltage limits.
• Provide suitable ventilation and thermal management for your application.
• This is a non-isolated DC-DC converter and is not intended for direct connection to household AC mains.
• Do not use it as a standalone battery charger without confirming that the complete circuit provides the charging and protection functions required by the battery.
• Actual product appearance may vary slightly due to manufacturing variations, lighting, and screen settings.
