5.5 Kit Modifications

SAM E54 Xplained Pro has several resistors that can be used to disconnect I/O pins of the ATSAME54P20A from connectors and on-board ICs, and to disconnect power signals.

Info: Note that there are some resistors that aren't mounted by default on the kit listed in the table below.
