The nPM2100 Power Management Integrated Circuit (PMIC) checks the status of the VSET pin at startup. Use a jumper on P8 which is labeled VSET to set the output voltage to either 1.8 V or 3.0 V.
The output voltage is software configurable in 50 mV steps from 1.8 V to 3.3 V.
The following figure and table show the schematic and function descriptions for VSET.

| Configuration | Pin header | Connecting jumper pins | Output voltage (VOUT) | |
|---|---|---|---|---|
| Output voltage | P8 | VSET | 3.0 V | 3.0 V |
| 1.8 V | 1.8 V | |||
