6.5.1 PCB Revision Marking
One thousand SAM V71 Xplained Ultra revision 8 kits have revision 3 PCBs (A08-2216) that are marked with "Revision 2" under the location of the serial number sticker.
These PCBs can be identified by the addition of the "USB VBUS" and "SUPER CAP" connectors shown in Figure 4-2 that were not present in revision 2 of the PCB.
