MCU data logger

MCU Data Logger PCB

A custom PCB designed in KiCad for an ATmega328P-based MCU Data Logger. This project demonstrates the complete PCB design workflow, from schematic capture and PCB layout to 4-layer stackup conversion and Gerber generation for fabrication.

Project Overview

This project includes:

• Complete schematic design
• Footprint assignment
• 2-layer PCB layout
• Conversion to 4-layer PCB stackup
• Design Rule Check (DRC)
• Copper pour
• Gerber generation
• Git version control

Design Workflow

• Created schematic
• Assigned footprints
• Imported netlist into PCB Editor
• Component placement
• Manual routing
• Copper fill
• Design Rule Check (DRC)
• Generated Gerber files
• Converted design to a 4-layer PCB stackup
• Generated final manufacturing files

Manufacturing Outputs

The repository includes:

• Gerber Files
• Drill Files
• Copper Layers
• Silkscreen Layers
• Solder Mask
• Board Outline

These files are located inside the Gerbers_4layers directory.

Tools Used

• KiCad
• Git
• GitHub

Learning Outcomes

Through this project, I gained hands-on experience in:

• PCB schematic design
• PCB layout
• Component placement
• PCB routing
• Copper pours
• Design Rule Checking (DRC)
• Gerber generation
• Multi-layer PCB stackup
• Git version control

Future Improvements

• Improve signal routing
• Power integrity optimization
• Differential pair routing
• High-speed design practices
• EMI/EMC optimization
