nRF51 DKDevelopment kit 

Bluetooth Low Energy development kit for the nRF51 Series

The nRF51 DK is a low-cost, versatile single-board development kit for Bluetooth Low Energy, ANT and 2.4 GHz proprietary applications on the nRF51822, nRF51422, nRF51824 and nRF51802 SoCs.

It facilitates development exploiting all features of the nRF51 Series SoCs. All GPIOs are available via edge connectors and headers, and 4 buttons and 4 LEDs simplifies input and out to and from the SoC.

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

It can be powered with USB, but also includes a CR2032 battery holder, enabling in-field testing of prototypes.

Keil, GCC and IAR IDEs and toolchains are supported, see this for more information.

The box includes an nRF51 DK, 5 x nRF51422 samples and a CR2032 battery. hardware layout and schematics are available.
