nRF52840 DK Development kit

Bluetooth Low Energy, Bluetooth mesh, NFC, Thread and Zigbee development kit for the nRF52840 SoC

The nRF52840 DK is a versatile single-board development kit for Bluetooth Low Energy, Bluetooth mesh, Thread, Zigbee, 802.15.4, ANT and 2.4 GHz proprietary applications on the nRF52840 SoC. It is the recommended Nordic development kit for Amazon Sidewalk. It also supports development on the nRF52811 SoC.

The nRF52840 DK can also be used for Matter over Thread where Thread is used for transport and Bluetooth LE for commissioning. Matter devices based on Thread are required to feature Bluetooth LE concurrently to enable adding new devices to a network.

It facilitates development by exploiting all features of the nRF52840 SoC. It includes an NFC antenna that quickly enables utilization of the NFC-A tag peripheral. All GPIOs are available via edge connectors and headers, and 4 buttons and 4 LEDs simplify input and output to and from the SoC. An on-board external memory is connected to the QSPI peripheral in the nRF52840 SoC.

It is Arduino Uno Revision 3 compatible, making it possible to mount 3rd-party shields with ease. It comes with an on-board SEGGER J-Link debugger allowing programming and debugging both the on-board SoC and external targets through the debug out header. It also interfaces directly with the Power Profiler Kit II.

The DK is typically powered with USB, but can be powered by a wide range of sources, within the supply range of 1.7 to 5.0 V. In addition to USB, it can be powered with an external source, but also includes a CR2032 battery holder and a Li-Po battery connector, for in-field testing. Current consumption can be measured by using the dedicated current measurement pins.
