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.

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
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
connector, which are carried out on a dual row, 10 pin, P2.54mm standard pin header, with the
following pinout.
