The nPM1304 EK provides connections for easy configuration and evaluation of the nPM1304 Power Management Integrated Circuit (PMIC) through the nPM PowerUP computer app available in nRF Connect for Desktop.
With the nPM PowerUP app, you can use the built-in battery models or you can generate your own battery model by using the EK. The generated battery model can be integrated with a host System on Chip (SoC) for fuel gauging.
