The nRF5340 DK is the development kit for the nRF5340 SoC.
Power Management IC (PMIC) with unique system management features
The nPM1300 is designed to provide highly efficient power regulation for Nordic’s nRF52® and nRF53® Series, as well as the nRF54H20 advanced wireless multiprotocol Systems-on-Chip (SoC). The PMIC is also suitable for battery charging for applications based on the nRF91 Series systems-in-package (SiPs) for cellular IoT, by using the PMIC’s unregulated output to power the SiP's internal buck regulators.
