3A Step-Down DC-DC Voltage Buck Converter Module - Jumpers for Voltage Setting

A mini step-down converter that changes the voltage from 4V to 24V - into freely adjustable voltage from 0.85V to 22V with a potentiometer. The system works only as a step down voltage.
Possibility to select the voltage by soldering a given jumper: 1.8V, 2.5V, 3.3V, 5V, 9V, 12V.
