ufl cable

[ozcal]

Hi guys, building a Rpi based music server that will use i2s transmission of signals to dac via ufl cables . Having trouble finding said cables in short lengths and also need to know the correct impedance of the cable (50 or 75 ohms).
Can anyone point me in the right direction, please .

You can buy them on aliexpress, search for u.fl cable on there.
Because they're often used for RF, the impedance of the cable used is 50 ohms.
