Tips:

1. Input and output cannot be reversed, or it will burn the module.

2. Input voltage much be more than 1.5V higher than output voltage. Can not used to boost voltage.

3. After wire connection, first to turn a dozen times, then adjust the voltage by anticlockwise rotation.

4. It is recommended to use within 2.5A current for long time work, and need to add heat sink if the current exceeds 2A(output above 10W).

Wire Connection:

1. Solder, weld the power cord directly to the input (output) port.

2. Welding Pin, can insert the pin with lead wire or insert into PCB, or welding on the PCB directly with pin.
