Great to hear.

The pinouts you require are the 5V, 3.3V, GND and then the I2C and I2S lines.

See this thread for more information :

Which microcontroller will you use ? How will you program ?

You can reference the Linux device tree for this sound card to work out which i2c address to use. You can reference the wm8731 linux driver to work out how to intialise the registers of the codec.

Hello All,

I'm planning to use the PI Sound Card with a card using a microcontroller.

I need the card schematic and the pinout names.

Any Help ?
