# Title: BT Audio Click Board™ ## Description: 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. Learn more from the vendor's datasheet. 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. Read about it in this tutorial. 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 The BT Audio Click Board™ has a 10m range in open space. The range is smaller indoors, but still enough to cover a few rooms. The BT Audio Click Board™ communicates with the target board MCU through the mikroBUS™ UART interfaces, with few additional pins. The board uses a 3.3V power supply only.

The HSP/HFP stands for Hands-Free Profile and Headset Profile for an audio connection between Bluetooth on your phone and the headset. The module is fully Bluetooth qualified and provides global modular approval. The ADC can sample up to 200 kHz using different inputs as sample triggers and it supports 8/10/12 bit resolution. Any of the 8 analog inputs can be used both as single-ended inputs and as differential pairs for measuring the voltage across them. The ADC supports full 0 V to VCC input range. The BT Audio click runs on 3.3V power supply only. ## Product type: Click Board ## Vendor: Mikroelektronika d.o.o. ## Tags: Audio, Bluetooth, BT/BLE, Click Board, MikroE, Wireless ## Price range: 41.3 - 41.3 GBP ## Link: https://thedebugstore.com/products/mikroe-2399-bt-audio-click-board-uk ## Compare-at price range: 59.0 - 59.0 GBP ## Options - Title: Default Title ## Collections - [New Products](https://thedebugstore.com/a/llms/collections/new-products-debug-store) - [Mikroelektronika d.o.o.
