README
README.mdESP32 Dev Board Project
The ESP32 Dev Module is a powerful microcontroller with built-in Wi-Fi and Bluetooth, widely used for IoT and embedded applications.
This project includes the schematic and PCB design of an ESP32 Dev Module created using KiCad.
The schematic defines connections for power, EN pin, and basic components like resistors and capacitors.
A 2-layer PCB is designed with proper routing and clearance rules followed.
KiCad is used for schematic capture, footprint assignment, and PCB layout, and Gerber files are generated for manufacturing.

Questions
How big is the ESP 32 DEV KIT PCB Layout PCB?
It measures 30.5 × 56.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ESP 32 DEV KIT PCB Layout use?
34 parts, built around the CP2102N-A01-GQFN28R, ESP32-WROOM-32, AMS1117-3.3 and MMSS8050-H-TP. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ESP 32 DEV KIT PCB Layout KiCad files?
From the RTX17LEO/ESP-32-DEV-MODULE repository on GitHub, at the commit this page was made from: the board is ESP 32 DEV KIT PCB Layout.kicad_pcb and its schematic ESP 32 DEV KIT Schematic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP 32 DEV KIT PCB Layout design in my own project?
Its repository states no licence, so its author keeps all rights: ask RTX17LEO before reusing the design.
