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.
