Product description: nRF5340-DK - development kit - Bluetooth / Thread / ZigBee / Matter / NFC - Nordic Semiconductor
The nRF5340-DK is Nordic Semiconductor's professional development kit designed for prototyping IoT devices, automation systems, wearable electronics, and industrial applications. At the heart of the board is the nRF5340 SoC , which combines a powerful 128 MHz Arm Cortex-M33 application processor with a low-power 64 MHz Arm Cortex-M33 network processor. The platform supports multiple wireless communication standards, including Bluetooth 5.4, Bluetooth LE, LE Audio, Thread, ZigBee, Matter, NFC, ANT, and 802.15.4 . The kit includes a built-in SEGGER J-Link OB programmer and debugger, four programmable buttons, four LEDs, a Li-Po connector, a CR2032 battery holder, and current consumption measurement pins. Compatibility with Arduino Uno Rev3 allows for easy expansion of the board's functionality with additional shields and modules. The nRF5340-DK works with the nRF Connect SDK , which integrates the Zephyr RTOS, drivers, examples, and protocol stacks.
