nRFnRF52840-DK
Overview
The nRF52840-DK is Nordic Semiconductors evaluation and development kit for the nRF52840 SoC, a feature-rich SoC for Bluetooth 5 and other low-power 2.4 GHz protocols. The board includes an on-board Segger J-Link programmer/debugger, USB connectivity, and Arduino Uno R3 compatible headers to simplify prototyping. It is intended for developing Bluetooth Low Energy, mesh, Thread/Zigbee and USB-capable applications.
Why Choose This Part
The DK exposes most of the nRF52840s signals and peripherals while providing an integrated Segger J-Link on-board debugger for immediate programming and debugging. Its Arduino-compatible headers and USB connectivity make it convenient for rapid prototyping and testing of wireless and USB applications. Choosing this kit gives access to Nordics software ecosystem (nRF Connect SDK and nRF5 SDK) and a wide range of reference examples.
Applications
Key Specifications
Getting Started
Connect the board to your PC over USB; the on-board Segger J-Link OB enables programming and debugging without extra hardware. Use Nordics nRF Connect SDK (Zephyr-based) for current examples and Thread/Zigbee development or the nRF5 SDK for legacy Bluetooth examples; Segger Embedded Studio and GNU Arm Toolchain are commonly used toolchains. Install nRF Connect for Desktop utilities (programmer, toolchain manager) and run a basic sample (blinky or BLE peripheral) to verify setup.
