Ethan Beaudoin developed foundational DriveJ2 PCB assets in the robotique-udes/PCB repository, focusing on manufacturability, testability, and design reuse for both 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. His work included reconfiguring arcs and segments, reassigning vias and layers, and updating amp-rating planes to support reliable prototyping. Using CAD, KiCad, and PCB design skills, Ethan delivered two features in one month, demonstrating depth in hardware design and readiness for manufacturing handoff without reported bugs.
