The purpose of this design guide is to support hardware, system, and firmware engineers implementing a product using either an AMD Kria™ K26 SOM or K24 SOM. The guide outlines electrical, mechanical, firmware, and power-on configuration design considerations that must be addressed as part of designing an AMD SOM compatible carrier card. The document is not intended to be self-contained, meaning that there are references to other AMD product documentation to help the reader find more detailed technical information available in corresponding technical reference manuals, software design guides, and thermal design guides. The Kria K26 and K24 are designed to be mechanical and electrically compatible to allow scalability between the two SOMs.
