CosmoQuiz

On Day 1, I researched components like the ESP32-S3, ILI9488 TFT display, and MAX98357A amplifier to design a custom Game Machine PCB. After learning KiCad’s schematic workflow and mastering practices like net labeling, I built the Version 1 schematic. Due to insufficient component documentation, I excluded the MCP IO expander and used placeholders for the display and step-up converter. Despite software troubleshooting with Git and WakaTime, I successfully passed the Electrical Rules Check with zero errors or warnings. Finally, I committed the project to GitHub, ready for footprint assignment and PCB routing.
