Is there a max length for a cable that can be used with the included microphone once it is detached from the board? Are there suppliers for a longer cable? Thank You for insights.
This cable is quite common if you search on amazon “5 pin cable 1.25mm” for example this one, assuming that you are located in the USA:
Another solution is to use the existing cable and solder on extension on each end.
But it’s an I2S bus it’s not really documented how long it could be if I add to guess i would say one meter max.
