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. Of course, you'll need to make sure that you have a nice strong 5V power supply so make sure to add 500mA or more to your power supply requirements!

This board also works very well with boards that don't have audio like the Pi Zero

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
