How to use
The module has four terminals as screw connectors:
| Pin | Description |
|---|---|
| IN+ | Input voltage - positive pole. |
| IN- | Input voltage - negative pole (ground). |
| OUT+ | Output voltage - positive pole. |
| OUT- | Output voltage - negative pole (ground). |
The output voltage is adjustable from 3.2 V to 35 V using a potentiometer. Note that this is a step-down circuit, so the output voltage cannot exceed the input voltage.
