NRF52840 Bluetooth? 5 Evaluation Board[Video]: Datasheet, Nrf52832 VS Nrf52840, and Applications

The nRF52840 is an advanced, highly flexible single-chip solution for today’s increasingly demanding ULP wireless applications for connected devices on our person, connected living environments, and the IoT at large. It is designed to be ready for the major feature advancements of Bluetooth® 5 and takes advantage of Bluetooth 5’s increased performance capabilities which include long-range and high throughput modes. Inherent industry-grade security is essential in today’s applications. The nRF52840 adds best-in-class security for CortexTM-M Series with an on-chip ARM® CryptoCell cryptographic accelerator.

The nRF52840 employs the same hardware and software architecture as existing nRF52 Series SoCs. At its core is an ARM Cortex-M4F processor allowing quicker and more efficient computation of complex functions for DSP and those requiring floating-point math.
