Overview
ESP is an open-source printed circuit board by Az154za, from the Az154za/ESPY repository on GitHub. It is a 2-layer board of 45.5 × 28.5 mm with 16 parts on 45 nets, routed with 91 tracks and 32 vias.
It is built around the ESP32-S3-WROOM-1-N8 and AMS1117-3.3. Its parts include 6 capacitors, 4 resistors, 2 ICs, 2 connectors and 2 switches. It belongs with the ESP32 boards of this library.

README
README.mdESPY:
The main mcu is the esp32-P4 that allows fast lane data transmission allowing the camera and display option . This project contains 4 layers 2 for signals 1 for 3V3 and one for Ground .
The reason I chose the p4 is because it's very good for cameras .

Questions
How big is the ESP PCB?
It measures 45.5 × 28.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP use?
16 parts, built around the ESP32-S3-WROOM-1-N8 and AMS1117-3.3. 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 KiCad files?
From the Az154za/ESPY repository on GitHub, at the commit this page was made from: the board is prototype/ESP.kicad_pcb and its schematic PCB/ESPY.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP design in my own project?
Its repository states no licence, so its author keeps all rights: ask Az154za before reusing the design.
