Vibe-Coding a PCB – surprisingly good
I was expecting this to be pretty bad - but it actually came out quite nicely!
For this experiment, I used Atopile — a tool that lets you define a hardware project using code and turns it into a KiCad PCB. The board needed the basics: an ESP32-S3 module, USB-C power and data lines, a 3.3V regulator, reset and boot buttons, status LEDs, a quick connector, and the usual passives. I specified LCSC part numbers and 0603 sizes for resistors and capacitors, with GPIO 19 and 20 handling the USB data lines for proper differential routing.
