3.7.1 SOM Board to Board Connectors (33)

The Open-Q 845 µSOM connects 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 the list of signals exposed by the SOM, see the device specification
(Ref. R-1).

3.7.2 Boot Configuration DIP Switch S2600 (37)

There is a DIP switch S2600 on the top side of the Open-Q 845 carrier board. The 8-bit switch
allows the user to control the system configuration and boot options. The image below shows the
DIP switch assignments.
