Development Board Schematics and Revision Information


The MitySOM-A10S Development Kit supports Critical Link’s Arria 10 SoC based modules.

The kit comes with a MitySOM-A10S module of your choice and includes a base board that features an array of interfaces and expansion headers such as USB, Debug RS232 to USB Console, FMC Expansion Connector, PCI-e x4 Expansion Header, MMC/SD Card switch and Gigabit Ethernet interfaces. The schematics are available on this page in a PDF format in order to aid in the development of the interfaces offered.

The table below is chronological and maps the board part number, including Gen 1 and Gen 2, to the schematic and a brief description of the change from the previous revision.

NOTE: You must have a valid registered account and be logged-in in order to download the schematics.

Altium Design Files: Customers who have purchased the development kit and are designing a custom base board to use the MitySOM-A10S can request the Altium Design Files from Critical Link by e-mailing
