Key features
- Dedicated Universal Serial Bus (USB) Type-C connection powers the nPM1304 PMIC
- Battery connectors support Negative Temperature Coefficient (NTC) thermistor connection for monitoring battery temperature
- Male pin headers and probe loops provide easy access to PMIC voltage outputs
- No hardware changes are needed to measure key parameters
- Exposed jumper pins to do the following:
- Select VSET configuration (resistor, external, or off)
- Connect to General-Purpose Input/Output (GPIO)s
- Configure load switches or Low-Dropout Regulator (LDO)s
- Connect LEDs
- Configure the onboard active load
- Onboard nPM Controller circuit for PMIC configuration when connected to a computer
- Plug-and-play connection to nPM PowerUP, which is a computer app that enables quick evaluation and implementation of Nordic PMICs
- Evaluation possible without writing code or programming the device when using nPM PowerUP
- Use with a Nordic Development Kit (DK) or develop your own nPM1304 application
- Use with your own custom hardware or develop your own nPM1304 application
