Pinout and Functions
| Designation | Function |
|---|---|
| IN+ | Power supply input - positive pole |
| IN- | Power supply input - negative pole (ground) |
| OUT+ | Output voltage - positive pole |
| OUT- | Output voltage - negative pole (ground) |
The layout of outputs and inputs, along with the marked voltage polarity, is shown in the figure below:

The presence of output voltage is indicated by the LED - PWR. The LED will light up if the output voltage is higher than 2 V

Setting the output voltage value
The output voltage of the Kamod LM2596 module is smoothly regulated by a potentiometer in a very wide range.
The input voltage must be about 1.5 V higher than the assumed output voltage.

Dimensions
The dimensions of the KAmod LM2596 board are 43x21 mm, and the height is about 14 mm.
