The ATSAME54P20A has a built in two channel Inter-IC Sound Controller (I
2
S).
There is no on-board IC connected to this module, but the signals are available on the different pin-
headers on the kit as shown in the table below.

Info:
1) Soldering is required to connect these pins to the camera connector. The resistor footprint
R205, R206, R207, and R208 have to be populated by 0-ohm resistors. The location of the
footprints can be found in the Kit Modifications chapter.
Info: The I
2
S module can use more pins than listed in the table above. These signals are not
listed in the table as they are shared with the on-board QSPI Flash and CAN transceiver.
