Circuit Design and Fabrication

PCB design portfolio covering schematic capture, routing, board preview, and fabricated prototypes.

Overview

This portfolio entry collects PCB design and fabrication work across multiple embedded projects. It demonstrates schematic organization, component placement, routing, board review, and manufactured-board validation. The work shows the ability to move from idea to schematic, layout, fabrication, soldering, and testing.
