4.4 Zero Ohm Resistors
SAM V71 Xplained Ultra has several zero ohm resistors that can be used to disconnect I/O pins of the ATSAMV71Q21 from connectors and on-board ICs and to disconnect power signals. All Arduino pin numbers are listed in Arduino Connectors. Table 4-33 lists all zero ohm resistors on the kit. Figure 4-3 and Figure 4-4 shows where they are located.
Info: Note
from Table 4-33 that there are some zero ohm resistors that aren't
mounted by default on the kit.
