1.1 Introduction
This document is created to guide users to design GEA M6UL compliant carrier board. It will focus only on the interfaces in GEA M6UL
pinouts and related peripherals.
This document helps walk hardware designers through the various stages of designing a carrier board on this platform. Using this
document, hardware designers can efficiently locate the resources they need at every step in the board design flow.
All examples of this document are based on GEA M6UL carrier board that is available from ENGICAM. This document also provides a
collection of useful documentation, application reports, and design recommendations.
