The Port P2_[7:1] lines that are used for SDHC interface signals are also shared with the M.2 connector (J12)
signals and the PWM signals on the Arduino compatible header (J3). Zero-ohm onboard resistors are used to
allow the selection of signals between the SDHC card slot or the M.2 connector. The Arduino-compatible header
sockets are connected by default, however, can also be disconnected easily by removing the appropriate zero-
ohm resistors.
Figure 17 shows the zero-ohm resistor connections for uSDHC signals selection.
