Mini-PCIe Socket
SOM Header (J7 & J9)
The System on Module (SOM) with the CPU, DRAM and Flash connects to the
baseboard. There are roughly 180 pins between the 2 sockets. The system is not
designed in a way that the SOM would be removed and the user would interface with
connectors directly. If more information is required, please contact Gateworks support.
Test Header (J8)
This is for internal Gateworks use. Please contact Gateworks technical support with any
further questions.
Battery Coin Cell Socket (J12)
The 6.8mm backup battery socket allows for easy replacement of the battery. A
rechargeable 6.8mm, 3V, 3mAH Lithium coin cell should be used when replacing the
battery. Replacement batteries can be ordered from Digi-Key with part number
728-1078-ND.
Gigabit Ethernet Port and Passive PoE Input Power (J13)
The Gigabit Ethernet Ports are available through a standard 8-pin RJ45 connector. The
connector also supports Full Wave Passive Power over Ethernet. The power inputs are
diode protected to prevent back feeding with other power inputs. The Passive PoE
architecture is discussed in more detail in Section 1 and the input voltage requirements
are listed in Section 3.
