nPM1304 EK Evaluation Kit

Evaluation kit for the advanced PMIC nPM1304 with battery charging and unique system management features.

The nPM1304 Evaluation Kit enables easy evaluation and programming-free configuration of the nPM1304 power management integrated circuit (PMIC). By connecting to the nPM PowerUP application in nRF Connect for Desktop, all nPM1304 settings can be easily configured via an intuitive graphical interface and exported as code for implementation in your MCU applications. 

  • Achieve seamless integration and code-free configuration through the nPM PowerUP desktop application.  
  • The male header provides all the necessary interfaces for the nPM1304 power management IC (PMIC), facilitating connection to Nordic development kits (DKs) and external test equipment.  
  • Integrated LED indicators and buttons allow for evaluation of the PMIC's built-in LED driver and general purpose input/output (GPIO) functions. 
  • Contains a 20mAh battery 

The kit itself comes with a JST battery connector for use with/without an internal NTC battery, and a male header for accessing all nPM1304 interfaces. Additionally, it integrates three LEDs and four buttons for easy evaluation of the PMIC's GPIO and LED driver functions. 

Users can directly use the pre-configured battery model in nPM PowerUP to initially evaluate the fuel gauge capabilities of the nPM1304. This fuel gauge solution relies on the battery model to achieve optimal state-of-charge accuracy. Battery modeling is a one-time operation, and the required programmable load circuitry is built into the nPM1304 evaluation kit.

Differentiated algorithm-based battery fuel gauge solution including battery health

Accurate fuel gauging is essential for any battery‑powered device, giving users clear and reliable insight into how much energy is left and helping avoid unexpected shutdowns.

Nordic’s fuel gauging provides accurate state of charge information for all supported battery types. Battery state of health is also supported for rechargeable batteries - tracking actual capacity and aging over time to understand how the battery performs throughout its lifetime. This deeper insight helps devices stay reliable for longer and makes rechargeable battery replacement more predictable.

By combining high accuracy with ultra‑low power operation - including zero power consumption in sleep - and low system cost, the Nordic algorithm-based fuel gauge solution delivers accurate battery information without extra components, licensing fees, or impact on battery life.
