PROFILE

Quinn Mulhern

Jagger worked on the Matthew0826/NULunabotics repository, focusing on hardware design and PCB development over a four-month period. He expanded and reorganized the component footprint libraries, integrating connectors and power monitoring components from vendors such as Hirose, JST, and Molex to support accurate layout and reliable assembly. Using KiCad, he improved schematic capture and PCB layout by refining silkscreen labeling, optimizing filled zones, and enhancing project structure for maintainability. His work included schematic updates, version control hygiene, and bug fixes, resulting in more flexible designs, faster prototyping, and improved manufacturability. The depth of his contributions enabled robust, scalable hardware development.

Monthly summary for 2025-04 (Matthew0826/NULunabotics): Key feature delivered: PowerBoard2 Connector Footprint Library Expansion. A comprehensive library of connector footprints (D-Sub, FFC/FPC, IDC, etc.) from Hirose, JAE, Harwin, Harting, JST, and Molex added to PowerBoard2 to support accurate PCB layout and reliable assembly. In addition, no major bugs recorded this month. The work reduces design iteration time and enables rapid prototyping with broader connector options. Technologies demonstrated include cross-vendor footprint integration, library architecture, and version-controlled development. Commit reference: 0d55445184ef575a86f4f2d0feb003a6eb7eff61.
