Expansion connector X8A, X9A
The expansion connectors X8A and X9A provide an easy way to add
other functions and features to the phyBASE. Standard interfaces such
as USB, SPI and I
2
C as well as different supply voltages and one
GPIO are available at the pin header rows.
As can be seen in
Figure 29
the location of the connectors allows to
expand the functionality without expanding the physical dimensions.
Mounting wholes can be used to screw the additional PCBs to the
phyBASE.
The expansion connectors share the SPI interface and the GPIOs of
the X-Arc bus with the display data connector X6. Therefore switches
7 and 8 of DIP-Switch S3 must be configured to map the signals to the
desired connector.
