I2S, also known as Inter IC Sound, is an electrical serial bus used to interface digital audio devices at the chip and
circuit board level. Note that I2S is not a "plug and play" protocol, and requires attention to technical details
such as clocking and wire layout. It is a solution that we make available for advanced DIYers with suitable
knowledge, skills and measurement equipment to use it.
For more information, please read the
I2S technical note
