Ethan Beaudoin developed foundational DriveJ2 PCB assets in the robotique-udes/PCB repository, focusing on manufacturability, testability, and design reuse for prototyping and production. He established a KiCad symbol library and base PCB layout, then refined the design through coordinate adjustments, connector styling standardization, and copper plane optimization to enhance electrical performance. Using CAD and PCB design skills, Ethan reconfigured arcs and segments, reassigned vias and layers, and updated amp-rating planes to support reliable prototyping. His work demonstrated a methodical approach to hardware design, delivering two features in one month and laying groundwork for future manufacturing readiness without addressing bug fixes.
