Nordic Semiconductor nPM1304 PMICs and corresponding evaluation kit bring power efficiency, flexibility, and intelligent system control to compact embedded applications. Whether users are prototyping wearables, biosensors, or other space-constrained designs, the nPM1304 delivers robust performance with minimal external components. The evaluation kit, paired with the Nordic intuitive PowerUP software, provides a code-free way to experiment with and configure the PMIC's features, including fuel gauging, watchdog, and dynamic battery profiling. All of this is delivered in a rugged yet tiny package, ready for development or deployment.
