How to use the blue potentiometer

Rotate clockwise, the voltage increases ,
Turn counterclockwise, voltage decreases

Tips :

Input and output cannot be reversed, or it will burn the module.
Input voltage much be more than 1.5V higher than output voltage.
This product is a step-down module ,Can not used to boost voltage.
After wire connection, first to turn a dozen times, then adjust the voltage by anticlockwise rotation.
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).
Do not reverse the input and output interface

The input voltage is equal to the output voltage, and when the output voltage cannot be adjusted, turn the potentiometer clockwise for about 10 turns.

Turn the potentiometer to activate the product.

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.

Connect the 3.2V-40V input power supply, the power indicator lights up, and the module works normally.
Rotate the potentiometer in small increments.
Use a multimeter to measure the output voltage.
Adjust the required voltage before connecting the circuit.
In order to ensure the stability of the product, the input and output voltage difference needs to be greater than 1.5V
This product has no reverse polarity protection, and incorrect circuit connection will cause product failure.

The installation of electronic modules requires basic knowledge and requires a certain electronic professional foundation and hands-on ability.

Real colors may slightly differ from the pictures, as it depends on specific monitor settings and light brightness.
