Part Number:WRL-0001
The RN52 (part number RN52-I/RM) Bluetooth audio module provides a fully integrated solution for delivering high-quality stereo audio in a small form factor. It combines a Class 2 Bluetooth radio with an embedded DSP processor, controlled and configured by simple ASCII commands and GPIO.

It integrates RF, a baseband controller, and DSP, making it a complete Bluetooth audio wireless link. The RN52 supports HFP/HSP, A2DP, AVRCP, SPP, and iAP profiles and includes support for codecs such as SBC, aptX®, and AAC. It provides a UART interface, GPIO, stereo speaker outputs, stereo microphone inputs, and a USB port.

For prototyping with the RN52, there is a new development tool, the RN-52-EK. This simple-to-use kit demonstrates the key features of the module allowing designers to quickly and easily evaluate and develop prototypes.
