Nordic Semiconductor nRF52840 Bluetooth Development Kit for nRF52840 SoC 2.4GHz NRF52840-DK

The Nordic Semiconductor Bluetooth Development Kit has access to all I/Os and interfaces via connectors and there are an integrated PCB trace antenna and an RFconnector for direct RF test measurements. There is also a connector for an external NFC antenna. The kit is compatible with the Arduino Uno Rev3 standard making it possible to use a wide range of 3rd-party shields during development. It comes with an on-board SEGGER J-Link debugger allowing programming and debugging both the onboard SoC and external SoCs through the debug out the header.
