1.0 OVERVIEW
This document describes the hardware and software setup for the Roving Networks RN-52-EK
evaluation kit. This kit contains the hardware you need to evaluate the RN52 Bluetooth audio
module. The RN52 module is mounted to an evaluation board that demonstrates the module’s
key features. The board contains:
• Dual-channel audio output and input
• Easy access to GPIO pins
• Built-in amplifier for stereo audio output
• 6 pushbuttons to control audio playback
•Status LEDs
• Connections for the programmer and UART interfaces
The RN52 supports the following Bluetooth profiles:
• A2DP stereo audio (sink mode with an SBC CODEC)
• AVRCP media player remote control
• HFP/HSP for accepting a phone call from a mobile phone
• SPP (allows the module to receive serial data over the UART)
• iAP profile discovery for iOS devices
You use the evaluation kit to configure and program the Bluetooth module using the command
interface, create connections, and transfer data. The command interface is made up of simple
ASCII commands. See “Resources & Related Documents” on page 12 for information on avail-
able documentation.
