3.The voltmeter can be turned off with switches on both sides, and it can be easily achieved by lightly touching the left button when not needed
4.Tap the right button to switch the input or output voltage measurements and has a light display which is being measured voltages, and the setting is saved, even if it is turned off and then on again
5.Adjustable output voltage range of 1.25V ~ 37V continuously adjustable(The input voltage must be 1.5V higher than the output voltage)

Package includes：
2 piece * LM2596 Step Down Buck Power Convert Module

Attention to use:
1.When the power exceeds 15W, please increase the heat sink
2.Some components of the product may heat up after prolonged operation with high current.Please do not touch directly to avoid burns.
3.When Use the Module at First Time,Please Check and Adjust the Voltage to Normal,Please rotate the potentiometer counterclockwise for more than 10 turns. Because the module leaves the factory, the default output voltage is around 20V
