IN-IN + input Positive Input Negative!
Positive output OUT + OUT-output negative
Input voltage range: DC 4.5V to 53V (input voltage must be greater than the output voltage to 1.5V or more high. Could not boost)
Output voltage range: DC 3V to 40V voltage is continuously adjustable, high efficiency (up to 92%) the maximum output current of 3A.
Measured 12V input, 5V output current is 1A load regulation rate of less than 1%

Note:
It's LM2596HVS Not LM2596S Chip.
This is the step-down module, the input voltage must be higher than the output voltage.
Output current is greater than 2.5A (or output power greater than 10W) to work long hours, please add heat sink.
