My First ESP32 PCB in EDA

Lately, I’ve been slowly learning more about electronics and embedded systems through small robotics projects. One of the most exciting milestones for me was designing my very first ESP32 PCB in EDA.

Before this, I mostly worked with sensors, mechanical design, and wiring prototypes by hand. PCB design always felt a little intimidating because there were so many small details to think about, such as power routing, capacitors, grounding, footprints, and component placement. But once I started, I realized it was actually a very creative process.

I learned why different capacitors are placed near the ESP32, how filtering and decoupling help stabilize the circuit, and how PCB layout affects signal quality and noise. Seeing the schematic slowly turn into a real board layout felt surprisingly satisfying.

The board is still simple, but it feels like an important first step. It also made me appreciate how mechanical, electrical, and software design all come together in robotics.

There’s still a lot for me to learn, but I’m excited to keep building and improving one project at a time.
