When the nPM1300 EK is used with custom hardware make sure they are compatible in terms of voltage and current specifications.
The configuration process is similar to the nRF5340
Development Kit (DK), though some board-specific steps might differ.
Note: If the host device on the custom hardware and the nPM1300
Power Management Integrated Circuit (PMIC) have different I/O reference levels, VDDIO
on the EK must be supplied by the custom hardware.
