Raspberry Pi Wiring
if you have a Raspberry Pi and you want higher quality audio than the headphone jack can provide, I2S is a good
option! You only use 3 pins, and since its a pure-digital output, there can be less noise and interference.
This board works very well with boards that
don't
have audio like the Pi Zero and is the easiest way to get quality audio
out
Connect:
Amp Vin to Raspbery Pi 3V or 5V
Amp GND to Raspbery Pi GND
Amp DIN to Raspbery Pi #21
Amp BCLK to Raspbery Pi #18
Amp LRCLK to Raspbery Pi #19

This technique will work with any Raspberry Pi with the 2x20 connector. Older Pi 1's with a 2x13 connector do
not bring out the I2S pins as easily
