The 96Boards specification calls for two Expansion Connectors, a Low Speed and a High Speed.

The DB8 meets this requirement for low speed and exceeds it by having two high speed connectors, please review section

6 for detailed information regarding the Low Speed Expansion Connector and section 7 for detailed information regarding

the High Speed Expansion Connectors.

The 96Boards specifications allows for additional functionality provided that all mandatory functionality is available and

there is no impact on the physical footprint specifications including height and do not prevent the use of the 96Boards CE

low speed and high speed expansion facilities

The DB8 implements additional functions, which are listed in the following sub-chapters.

The GPS implementation is based on Qualcomm WGR7640 GNSS RF receiver (U5) supporting GPS, GLONASS and

COMPASS. The APQ8096 communicates directly with the WGR7640.

Gigabit Ethernet is supported by Qualcomm AR8151 controller and uses an RJ45 as the physical interface.

The DB8 includes a mini PCIE (PCI express) connector. This enables integration of HW peripherals which are compliant to

the PCIE mini specification.
