AudioB I2S Bluetooth Digital Audio Receiver Module - I2S Master

If you want to build a digital Bluetooth amplifier board, AudioB I2S Bluetooth audio receiver module is a good choice for your project. This is a Bluetooth 5.0 stereo recevier module, I2S digital output and music resampling frequency is 48KHz. This module supports Apt-X, and is based on QCC3008. We breakout pins to 2x10 2mm space male pins. You can integrate it to your project easily. If you want a demo board. Please buy our TSA7010 Digital Bluetooth Audio Receiver. It's a AudioB I2S module + DAC board.

The module PIN7,8,9,10 are I2S output pins, I2S voltage 1.8V.

• 7 - GND
• 8 - BCK   I2S synchronous data clock, It's a 2.304MHz square wave signal.
• 9 - SD     I2S synchronous data output.
• 10 - LRCK   I2S word select, 48KHz. 1 - Left channel data, 0 - Right channel data.
• Setting switch: We set to I2S in normal state. Set to SPI when you need to program the module.

Note1: You need to set the on board switch to SPI when you program the module

Note2: You need to change this module from I2S master to I2S slave. if you want to use it on our digital audio amplifier boards.

Note:

1. Quick press S2 to switch to the previous song, long press to reduce the volume
2. Quick press S3 to switch to the next song, long press to increase the volume
3. Press S1 to play or pause
4. if there is an audio output, MUTE pin will be high level, otherwise, it will be low level.
