3.6 Open-Q 845 µSOM
The Open-Q 845 µSOM contains the core Snapdragon 845 architecture. Measuring in at 50mm x
25mm, the SOM is where all the processing occurs. It is connected to the carrier board via three 100
pin Hirose DF40 connectors which allows essential power rails and signals to be exposed for
supporting other peripherals and interfaces on the platform.
For detailed information about the Open-Q 845 µSOM, see the device specification noted as
reference document R-1.

3.7 Open-Q 845 Carrier Board

The Open-Q 845 Carrier board is a Mini-ITX form factor board with various connectors used for
connecting different peripherals. The table and sections below provide in depth information on the
carrier board properties, user interfaces, connectors, and expansion headers found on the carrier
board. This information is important for users wishing to connect other external hardware devices to
the Open-Q 845 µSOM Development Kit. Users must ensure that before connecting any hardware
device to the development kit, that it is compatible with the Open-Q 845 hardware specifications.
See Figure 1 for position on carrier board.
