With drunk components!
This is a single board esp32-s2 development board. with two neopixels and an on-board antenna.
It has drunk component placement and some nice freeform traces
The 2.54mm pitch can be fitten in breadboard and used nicely with jumpers
The programming can be done over USB-C ports
The scehmatic is easy and simple, giving people the maximum leverage :)

Questions
How big is the Esp32-s2-dev PCB?
It measures 23.4 × 45.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32-s2-dev use?
31 parts, built around the ESP32-S2 and WS2812B-2020. 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 Esp32-s2-dev KiCad files?
From the cyao1234/e32 repository on GitHub, at the commit this page was made from: the board is hardware/esp32-s2-dev.kicad_pcb and its schematic hardware/esp32-s2-dev.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32-s2-dev design in my own project?
Its repository states no licence, so its author keeps all rights: ask cyao1234 before reusing the design.
