If you want build a digital Bluetooth amplifier board, AudioB I2S Bluetooth audio receiver module can be a good choice for your project. This is a Bluetooth 4.2 stereo receiver module with I2S digital output and music re-sampling frequency is 48KHz. It is Apt-X supported.

It is based on CSRA64215. We have used breakout pins to 2x10 2mm space male pins. 

You can integrate it to your project easily. This module has a SMA connector.

You can connect an external 2.4G antenna with it.

If you want a demo board, please buy our TSA7010 Digital Bluetooth Audio Receiver. It's a AudioB I2S module + DAC board.

The module PINs 7,8,9,10 are I2S output pins:

  • 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. 

Note: You need set the on board switch to SPI when you are programming the module.
