When the nPM1304 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 nRF54L15
Development Kit (DK), though some board-specific steps might differ.
Note: If the host device on the custom hardware and the nPM1304
Power Management Integrated Circuit (PMIC) have different I/O reference levels, VDDIO
on the EK must be supplied by the custom hardware.
