nRF52840-DK pinouts and communication interfaces
The nRF52840-DK kit provides access to 48 GPIO lines , which can be used to support UART, SPI, I2C, PWM, ADC , and standard digital inputs and outputs . All key signals are connected to edge connectors and goldpins, facilitating quick connection of sensors, expansion modules, and prototype circuits. Compatibility with the Arduino Uno Rev3 format allows the use of many ready-made shields without the need to design additional adapters. The board enables communication in the 2.4 GHz band using Bluetooth 5.3, Bluetooth Low Energy, Thread, ZigBee, ANT, and IEEE 802.15.4 . An integrated PCB antenna is included on board. SWF RF connector for radio measurements and a connector for an external NFC antenna. This equipment allows testing of both classic wireless transmission and pairing, identification, and short-range communication functions.
Thanks to its compliance with the Arduino Uno Rev3 standard, a wide range of external modules (shields) can be easily connected to the board.
Power can be supplied via USB or external sources ranging from 1.7 V to 5 V.
Programming and development environments for the nRF52840-DK
The nRF52840-DK works with the official nRF Connect SDK , which is based on the Zephyr RTOS and provides access to libraries, examples, drivers, and communication stacks. The kit can also be programmed using Keil, IAR Embedded Workbench, and GCC tools . This makes the board ideal for both learning microcontroller programming and professional wireless device design. The built-in SEGGER J-Link OB programmer allows programming and debugging without additional hardware tools. Drag-and-drop programming via Mass Storage Device and UART communication via a virtual USB serial port are also supported. The OTA-DFU function allows for wireless firmware updates, which is particularly useful for off-the-shelf IoT devices operating in the field.
