Please notice that address lines (A0, A1 and A2) and Write Protect (WP) line can be manually set
by the customer using a dedicated switch (SW1), which is placed right near the I2C EEPROM
Socket.
Setting of these signals can be made according to the following table

3.3.16 Feature Connector
For further expandability of the system, on board there is an expansion connector, which is a
standard pin header, dual row, 28 pin, p2.54 mm.
On the pins of this connector, there are signals related to Watch Dog, I
2
C bus, SM Bus, thermal
and power management, so there is a wide chance of expandability using these general purpose
I/O buses.

3.3.17 SPI Pin Header
Further expandability can be obtained using SPI signals coming out form Qseven
®
golden finger
connector, which are carried out on a dual row, 10 pin, P2.54mm standard pin header, with the
following pinout.
