This module lowers the entrance voltage on the specified output voltage that You adjust through trimmer on the board. It very practical because by changing entrance voltage, output voltage always stays the same, but still the entrance voltage has to be at least 0.7V higher than the output voltage.
Voltage’s entrance is IN+ and IN-, while the exit is OUT+ and OUT- . A power supply is able only to put the voltage down, not up!
It does not have a protective diode in case of the wrong polarity, pay attention while connecting!
