Overview

The nRF52840-CKAA-R is a highly integrated System-on-Chip (SoC) featuring a powerful ARM Cortex-M4F processor and a multiprotocol 2.4 GHz radio. It supports a wide range of wireless protocols including Bluetooth 5.3, Bluetooth mesh, Thread, Zigbee, and proprietary 2.4 GHz stacks.

Why Choose This Part

This SoC is distinguished by its 1MB Flash and 256KB RAM, providing ample headroom for complex application logic and wireless stacks. It includes a hardware-accelerated cryptographic engine and an integrated DC/DC converter to minimize power consumption in battery-operated designs.

Applications

High-Performance Wearables
Ideal for smartwatches and fitness trackers requiring complex sensor fusion and low-power wireless data sync.
Smart Home Infrastructure
Acts as a concurrent multiprotocol bridge for Thread and Zigbee networks in smart locks and lighting controllers.
Secure IoT Gateways
Utilizes the integrated ARM TrustZone CryptoCell-310 to manage secure boot and encrypted communications.
Advanced PC Peripherals
Enables high-speed wireless mice and keyboards via its integrated full-speed USB 2.0 controller.

Getting Started

Development is primarily done using the nRF Connect SDK based on the Zephyr RTOS, with hardware debugging supported via the nRF52840-DK development kit. The Nordic Power Profiler Kit II is highly recommended for optimizing current consumption during software development.
