PCB Design Course with Raspberry Pi Pico

Learn PCB design by building projects using the Raspberry Pi Pico microcontroller.

🎓 Course Overview #

This course is a practical, project-based introduction to PCB design, created for freeCodeCamp and the NerdCave YouTube channel.

Instead of learning PCB design through abstract examples, you’ll design real boards, manufacture them, and bring them to life using the Raspberry Pi Pico.

By the end of this course, you will be able to:

• Design schematics from scratch
• Create custom PCB
• Understand real-world electronics design decisions
• Debug, assemble, and improve your own hardware

No prior PCB experience is required.

🧠 What You’ll Learn #

Throughout the course, you’ll learn:

• PCB design workflow (idea → Prototype → schematic → PCB → assembly)
• Raspberry Pi Pico & Pico W fundamentals
• Power regulation and protection
• Button matrices, LEDs, displays, and sensors
• Addressable LEDs (WS2812B / NeoPixels)
• USB, HID devices, MIDI, and Bluetooth basics
• Manufacturing considerations (DFM, tolerances, footprints)
• Common beginner mistakes (and how to avoid them)

🛠 Tools Used #

• PCB Design Software (EasyEDA)
• Raspberry Pi Pico / Pico W
• WS2812B LEDs
• Through-hole & SMD components
• Real PCB manufacturing and assembly

All designs, code, and files will be open-source.

🚀 Course Structure #

This course is built around 8+ real PCB projects.
Each project has its own dedicated page, covering:

• Project idea & design goals
• Schematic design
• PCB layout walkthrough
• Manufacturing files
• Firmware & testing
• Common mistakes & improvements

🔧 Design & Manufacturing Workflow #

All PCBs in this course are designed using EasyEDA and manufactured using JLCPCB.

EasyEDA is used for:

• Schematic capture
• PCB layout
• Footprint management

JLCPCB is used for:

• PCB fabrication
• Surface-mount assembly (when applicable)
• BOM and Pick & Place handling

This toolchain is chosen because it is accessible, reliable, and widely used by makers, students, and engineers.
