SBC-GPIO Connector (SBC-GPIO) 7.8
The SBC-GPIO connector is present on the SBC and used to interface the Battery Module. The two
connectors SBC-GPIO and SBC-Ext-Bat is positioned so that they fit a single 2x6 pin header connector on
the Battery Module.
SBC-External battery (SBC-Ext-Bat) 7.9
The two connectors SBC-GPIO and SBC-Ext-Bat is positioned so that they fit a single 2x6 pin header
connector on the Battery Module.
Pin 1 is Bat+, (same as pin 1 on the SBC connector on the Battery Module)
Pin 2 is Bat-, (same as pin 2 on the SBC connector on the Battery Module)
Note that Intel specifies that battery must be connected, however it is unspecified what is the risk of not
using battery. When battery is not connected, Kontron has not been able to find any problems except for
RTC not running.
Clear CMOS (CLR-CMOS) 7.10
