The nRF51 SDK is a Software Development Kit for the nRF51 Series of System on Chips (SoCs). It contains drivers, libraries, examples, and APIs for the nRF51 Series SoftDevices that along with a nRF51 series Development Kit or Evaluation Kit provide you with all the necessary tools you need to begin developing.

The nRF51 SDK documentation includes descriptions and other reference material to help you understand the various components of the SDK. Examples are provided for development purposes only, and should always be tested with your design.
