I2S format was used by several high end companies for digital data transfer between components but there is no industry standard. You have to compare the Nuprime I2S pins spec with other brand’s spec to ensure compatibility.
Usually most of the pins are compatible except PIN 14. If you have to choose a non Nuprime component with I2S port, please compare every pins (pins with NC are not used). We are unable to confirm or test other brand’s I2S compatibility.
