PCB Design 路 AutoCAD Electrical 路 Engineering Documentation

From circuit schematics and board layouts to control-panel drawings.

Altium Projects 路 KiCad Projects 路 AutoCAD Project


About my work

This portfolio brings together my PCB design and electrical drafting projects using Altium Designer, KiCad, and AutoCAD Electrical. It includes editable source files, design previews, and project documentation covering both individual circuits and control-panel practice drawings.

Featured collections

Collection Projects and deliverables
Altium PCB Projects Four designs: 5V LED indicator, 5V-to-3.3V LDO, tutorial LED board, and USB-C charger/boost converter. Sources, local libraries, and available manufacturing outputs.
KiCad PCB Projects Three practice designs: LED indicator, AMS1117-3.3 regulator, and NE555 astable LED blinker. Editable projects, schematic/board previews, and supplied Gerber/drill exports.
AutoCAD WTP Control Panel Practice drawings for system architecture, incoming power distribution, and CPU digital-output/relay wiring, with supporting symbols.

Design previews

USB-C Charger / Boost PCB
USB-C Gerber layer preview
KiCad 3.3V Regulator PCB
KiCad regulator PCB layer preview

Previews are generated from the actual supplied design files and Gerber layers.

Tools and workflow

  • Altium Designer: schematic capture, PCB layout, local component libraries, and fabrication documentation.
  • KiCad: schematic-to-board practice projects, component placement, routing, and Gerber exports.
  • AutoCAD Electrical: electrical drawing organization, PLC output wiring, and control-panel drafting.
  • Documentation: project overviews, editable files, visual previews, and recorded design-check status.

Project notes

Practice and tutorial-based work is identified in the project documentation, with the original learning reference credited. Saved design-check reports describe the recorded design state; hardware fabrication, bench testing, and commissioning are not claimed.
