The DK supports development with an extensive range of wireless protocols. It supports Bluetooth Low Energy with features such as high-throughput 2 Mbps, Advertising Extensions and Long Range. Mesh protocols likeBluetooth mesh, Thread and Zigbee can run concurrently with BluetoothLE, enabling smartphones to provision, commission, configure and controlmesh nodes.
NFC, ANT, 802.15.4 and 2.4 GHz proprietary protocols are alsosupported.The DK is bundled with an NFC antenna that quickly enables testing ofnRF5340’s NFC-A tag functionality. A SEGGER J-Link debugger is on theboard, enabling full-blown programming and debugging, of both thenRF5340 SoC and external targets.All analog and digital interfaces, and GPIOs are available via headers andedge connectors.
The kit is Arduino Uno Rev3 hardware compatible, meaning it can be easily interfaced with external device shields.Four buttons and four LEDs simplify input and output to and from thenRF5340 SoC, and are all user-programmable.
An on-board external memory is connected to the 96 MHz QSPI peripheral in the nRF5340 SoC.The nRF5340 DK is typically powered via USB, but can be powered by awide range of sources, within the supply range of 1.7 to 5.0 V. In addition toUSB, it can be powered with external source, but it also includes a CR2032battery holder and a Li-Po battery connector, for in-field testing. Currentconsumption can be measured by using the dedicated current measurementpins, for example by using Nordic’s Power Profiler Kit II.
