nRF Cloud Support

Complete cloud infrastructure

All Nordic Bluetooth LE SoCs can take advantage of nRF Cloud's simple integration, providing essential services like device management and FOTA updates from day one of your project. Power and memory optimized specifically for Nordic devices, nRF Cloud gives developers the tools they need to manage, debug, and monitor their devices in the field without spending months building custom cloud infrastructure.  

Compatible PMIC and RF FEM options

calendar nPM1100 PMIC

Ultra-small form-factor Power Management IC (PMIC) for charging batteries and power delivery

The nPM1100 is a dedicated power management IC (PMIC) with dual-mode configurable buck regulator and integrated battery charger. It is designed as a complementary component to Nordic’s nRF52® Series and nRF53® Series System-on-Chips (SoCs) to ensure reliable power delivery and stable operation, whilst maximizing battery life through high efficiency and low quiescent currents. It can also be used as a generic PMIC device for any other suitable application. Its extremely compact form factor makes it ideal for advanced wearables, connected medical devices, and other size constrained applications. PCB area usage can be as low as 23 mm2.
