Kevin Zhang worked on schematic improvements for the ISS-PCB repository, focusing on refining the Debug LED and User Button components. He updated the User Button’s capacitance to ensure correct electrical characteristics, addressing reliability and testability in the design. Using Kicad and his expertise in electrical and electronics engineering, Kevin aligned schematic changes with prototype build and test plans to streamline validation and reduce rework. While the work spanned a single feature and did not involve bug fixes, it demonstrated careful attention to electrical clarity and maintainability, laying a solid foundation for future hardware iterations and smoother prototype testing cycles.
