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.

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.
