Worked on the PROVES_Cosmic_Watch hardware within the BroncoSpace-Lab/CADENCE repository, focusing on PCB design refinements and power routing improvements. Applied skills in CAD, KiCad, and electronics engineering to update the PCB layout, enhance grounding, and add mounting holes for better manufacturability. Improved silkscreen clarity and introduced 5V vias near critical power pins to strengthen power delivery and reduce production risk. Removed obsolete hardware artifacts to streamline the repository and prevent confusion during prototype development. These efforts supported faster, lower-risk hardware iterations and ensured clearer production handoffs, demonstrating a methodical approach to hardware design and artifact management.
