Description

Instruction to use

Please turn the potentiometer trimmer on the module and measure the voltage level using a multimeter (set the voltmeter 20V mode) to adjust the output voltage from this module. You may need to turn the potentiometer trimmer many times to see the changes in output voltage, turn right to increase the voltage level or turn left to decrease the voltage level. Soldering is required to use this module!

To allow this module to steadily output more than 2A, please add heatsink on top of the LM2596S chip, otherwise it will be overheat and trigger thermal shutdown.
