From the project

PCB design project using KiCad 9: single-sided 5V regulated power supply with LM7805, full design workflow from schematic to Gerber files.

A compact single-sided 5V regulated linear power supply designed using KiCad 9 and built around the LM7805 voltage regulator.

This project was developed as part of my PCB design learning journey to gain hands-on experience with the complete hardware development workflow—from schematic capture and PCB layout to electrical verification, 3D visualization, Gerber generation, and project documentation.
