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

The module’s PINs 7, 8, 9, and 10 are I2S output pins with an I2S voltage of 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 it to I2S in the normal state. When you need to program the module, set it to SPI.

Note: 

When you program the module, you need to set the onboard switch to SPI. If you want to use this module on our digital audio amplifier boards, change it from an I2S master to an I2S slave.

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, the MUTE pin will be at a high level; otherwise, it will be at a low level.
