Nordic Semiconductor nRF52833 DK nRF52833 Development Kit for nRF52833 SoC nRF52833 DK

The nRF52833 DK is an affordable single-board development kit for development of Bluetooth® Low Energy, Bluetooth mesh, Thread and Zigbee applications on the nRF52833 SoC.
The kit is hardware compatible with the Arduino Uno Rev3 standard, making it possible to a wide range of 3rd-party shields that are compatible with this standard, including the Power Profiler Kit from Nordic Semiconductor.
An included NFC antenna can be connected the kit to use the on-chip NFC-A tag functionality. The kit allows access to all I/O and interfaces via connectors and has 4 LEDs and 4 buttons which are user-programmable.
The DK can be powered via USB, but also supports Li-Po and CR2032 coin-cell batteries, which enables in-field testing of prototypes.
And on-board SEGGER J-link debugger allows programming and debugging both the on-board SoC and external SoCs through the debug out header.
