used for 2x20 pin connectors only.
Figure 8. 2x20 Pin Connector
The signal mappings are as indicated in the table shown in Figure 8 . All the signals are referred to by the
pin number in the SDK, and Figure 8 shows the default mappings. Note that some of the pins are
repeated across the connector. For instance, pin 62 is available on P1 and P4, but only P1 is connected
by default. The signal on P4 is marked with a *(star) to signify that it is not connected by default and can
be routed to the pin by using a 0
Ω
resistor in the path. For the exact resistor placement, see the
schematics and placement diagram .
