Bluetooth class 2 radio and DSP processor combined

Microchip’s RN52 Bluetooth audio module delivers high quality audio in small form factor (26.0 mm x 13.5 mm x 2.7 mm). The module combines a class 2 Bluetooth radio and an embedded DSP processor, controlled and configured by simple ASCII commands.

BT Audio Click can stream audio files

DSP, or digital signal processor, is what makes this module special, because it can actually stream audio – it converts and compresses the radio waves sent from your phone or computer into digital data, and then sends it to your speakers or headphones.As a use case example, we built a multimedia station project.

Quality of sound over Bluetooth

The module supports aptX, audio codec for high quality stereo audio streaming over a Bluetooth connection. So the quality of the sound is not something you will have to compromise on, as aptX encodes a CD-quality (16-bit / 44.1kHz) audio stream.

The RN52 module supports HSP/HFP, A2DP, AVRCP and SPP, as well as digital I/O, stereo speaker output, stereo microphone input. The module also supports iAP profile discovery for connecting the BT Audio click to Apple devices like, iPods, iPhones or MAC computers.HSP/HFP stands for Hands-Free Profile and Headset Profile for an audio connection between Bluetooth on your phone and the headset.

Bluetooth range

BT Audio click has a 10m range in open space. The range is smaller indoors, but still enough to cover a few rooms.BT Audio click communicates with the target board MCU through the mikroBUS™ UART interfaces, with few additional pins. The board uses a 3.3V power supply only.
