Dive into the second part of a comprehensive tutorial on creating a custom Raspberry Pi Compute Module 4 (CM4) carrier board using KiCad. Continue the design process by setting board parameters, arranging footprints, and routing various components. Learn how to calculate and implement USB differential pair traces, route power and data lines, add ground pours, and perform design rule checks. Explore the process of generating gerber files and a bill of materials for manufacturing. Gain insights into PCB design considerations, including ESD protection, component placement, and routing techniques specific to the CM4 form factor. Follow along as the instructor demonstrates each step, from layout refinement to preparing files for production, providing valuable knowledge for embedded system designers and hobbyists alike.
