GPIO Pin mappings required for I2S to LVDS Board on VIM3

@Gouwa @Terry @tsangyoujun
Need your advice to map the pins correctly for the board given below. GPIO pinout given in Khadas VIM3 schematic is kind of cryptic for me. I am just a tinkerer :smiley:
Use Case: Running Volumio and want to connect DAC through I2S.

Could you please specify the correct GPIO pinouts corresponding to the I2S to HDMI board.

  1. DATA >> ??
  2. BCK >> ??
  3. LRCK >> ??
  4. MCLK >> ??
  5. DSD_ON >> ??
  6. +5v >> GPIO Pin 1
  7. GND >> GPIO Pin 21

Thanks in advance!

  1. DATA >> I2SB_SDO
  2. BCK >> I2SB_SCLK
  3. LRCK >> I2SB_LRCK
  4. MCLK >> I2S_MCLK0

About the DSD_ON pin on your board, you need to check it by yourself.
Maybe is the low level or high level.
