On-Module Trace Lengths¶
This page provides information about routing guidelines / rules used on the MitySOM-AM62, MitySOM-AM62A, and MitySOM-AM62P modules. that may be beneficial to carrier board designers.
Trace Groups Matching¶
The following trace groups are routed on the module from the AM62x/AM62A/AM62P processor to the edge connector fingers.
