Adding USB board in a dac

[gillougillou]

I am looking to add an USB imput in my dac.

But I can’t found how to connect it.

Perhaps some one has information about how to connect thé I2s wires ?

Thank you, Gilles.

The picture of the connector on the dac board is too blurry to read the printing on the board.

Also, it would help to know what dac board it is, and what dac chip is used on it.

On your DAC board from left to right you have GND MC LRCK BCK DATA across 5 pins.

On your USB interface board you have, from right to left GND MC LRCK BCK DATA (ignore the 6th pin)

So place wires from right to left on the USB board and left to right on the DAC board.

Is the MC frequency output by the USB board the same as what the dac chip(s) need?

Also isn’t there a left/right justified factor as well?

Most USB boards are I2S format, but some are configurable for LJ, RJ, different bit-depths, etc.
