nPM1304 EK Evaluation Kit

Evaluation kit for the nPM1304, a highly integrated Power Management IC (PMIC) with battery charging and advanced system management features

The nPM1304 Evaluation Kit (EK) enables fast evaluation and code‑free configuration of the nPM1304 PMIC using the nPM PowerUP desktop application in nRF Connect for Desktop. Through an intuitive graphical interface, all PMIC settings can be configured and exported as code for direct integration into the host MCU application. 

The EK provides male pin headers for access to all nPM1304 connections, allowing easy connection to Nordic Development Kits (DKs) and external test equipment. Integrated LEDs and pushbuttons enable evaluation of the PMIC’s built‑in LED drivers and GPIO functionality, while JST battery connectors support batteries with or without an internal NTC. A 20 mAh battery is included for immediate evaluation. 

For fuel‑gauge evaluation, users can start with pre‑profiled battery models included in nPM PowerUP. For best state of charge and state of health accuracy, battery profiling and model generation is a one‑time process, and the nPM1304 EK includes the programmable load circuitry required to perform this profiling directly—no external fuel‑gauge board is needed.

nPM PowerUP

nPM PowerUP is a desktop application for controlling the nPM1304 Evaluation Kit (EK). Once connected to an EK, the app gives full control over the adjustable settings of the nPM1304 PMIC. Using the included battery models, you can also get an estimated time-to-full and time-to-empty when charging or discharging a battery connected to the EK. 

nPM PowerUP is found inside nRF Connect for Desktop.
