From Concept to Manufacturing: Build, Test, and Deliver a Four-Layer IoT PCB Using KiCad 9

Updated July 2025

I’ve just published the complete, uncut layout design session for the ESP32 KiCad 9 project as a single video.

This video shows the entire layout process from start to finish — including every step, every fix, and all decisions made in real time.

I decided to publish this video after several students asked me a real-time version of the parts of the original lectures where I used fast-forward to speed up parts of the process that I originally considered boring and repetitive.

I hope that it will help you gain a deeper understanding of how the design was built, how I troubleshoot problems, and how I handle real-world layout challenges.

Updated March 2025

I recorded a series of lectures where I redesigned my ESP32 board to fix issues from the first prototype. You will find the new lectures at the end of the course.

I modified the audio and light sensor wiring to both use ADC1, integrated a variable resistor into the audio amplifier for adjustable gain, and corrected the photosensor wiring with proper capacitor placement. I also updated the PCB layout by enlarging the buttons, refining the track routing, adding a ferrite bead to reduce noise, and updating component footprints and 3D models.

About this course

Unlock the full potential of KiCad 9 and learn how to design a fully functional IoT PCB from start to finish. In this comprehensive, project-based course, you will work through the complete design, testing, and manufacturing process of a four-layer PCB using KiCad 9's latest tools and techniques. By the end of the course, you will have a fully designed and tested ESP32-based IoT board, along with the skills to tackle your own advanced PCB design projects.

What You Will Learn:

• Design a complete four-layer PCB with KiCad 9.

• Create schematics, assign footprints, and route tracks for high-speed signals like SPI, I2C, and USB.

• Implement power and ground planes, copper zones, and via stitching for signal integrity.

• Troubleshoot and resolve design issues using KiCad's Electrical Rules Check (ERC) and Design Rules Check (DRC).

• Run Design for Manufacturing (DFM) checks with NextPCB to ensure production-ready designs.

• Test and validate key PCB components such as an SD card interface, flash memory, sensors, microphone, and OLED display.

• Analyze analog and digital signals using test scripts, an oscilloscope, and KiCad's simulation tools.

Course Deliverable:

By the end of the course, you will have a fully functional ESP32-based IoT PCB, including:

• A professionally designed four-layer PCB, ready for fabrication and assembly.

• Complete KiCad project files for your reference and future use.

• Practical skills to design advanced PCBs for IoT applications.

• Insights into troubleshooting common design issues and preparing files for manufacturing.
