nRF2460 Development Kit User Guide
1
Introduction
The nRF2460 Development Kit is the recommended starting point for developing a new product based on
the nRF2460 Wireless Mono Audio Streamer. The nRF2460-DK used in conjunction with the nRFgo
Starter Kit (sold separately) is the ideal platform to help you through each stage of the development
process. The nRF modules of the nRF2460-DK can run stand-alone with external power supply for simple
evaluation, or placed into an nRF module socket on an nRFgo Starter Kit Motherboard to evaluate all the
features of the nRF2460. Available headers on the nRF2460-DK make it easy to connect an external audio
codec or MCU while developing a product.
1.1
Who should read this user guide?
Anyone developing a product based on the nRF2460 should read this User Guide. It describes all the
features of the nRF2460 Development Kit from how to use the pre-compiled firmware in order to evaluate
the nRF2460 module, to how to connect external MCU or codec during prototyping of your own hardware.
To fully understand this User Guide a background in software development and/or electronic engineering is
required.

Development Kit content
The nRF2460 Development Kit is based on the nRFgo development platform, and consists of nRF
modules that can be plugged into an nRFgo Starter Kit Motherboard during development and evaluation.
You can download all the necessary software and documentation from Nordic Semiconductor’s website at
www.nordicsemi.com.
The nRFgo compatible nRF2460 Development Kit contains the hardware, software and documentation
components outlined in sections
2.2
and
2.3.
Figure 1. Kit content
2.1
Hardware content
The nRF2460 Development Kit consists of one nRF2460 module with a PCB antenna, two nRF2460
modules with an SMA connector, two external 2.4 GHz swivel antennas, and five samples of the nRF2460
IC (integrated circuit).
