Overview
The nRF52 Series of System-on-Chip (SoC) devices embed a powerful yet low-power Arm® Cortex®-M4 processor with our industry leading 2.4 GHz RF transceivers. In combination with the very flexible orthogonal power management system, and a programmable peripheral interconnect (PPI) event system.It offers pin-compatible device options for Bluetooth® Low Energy, proprietary 2.4 GHz, and ANT™ solutions.
