This bare minimum board uses the ESP32-S2 module, it is designed to use minimal amount of current during sleep. All signals are routed to the edge of the PCB, it is also designed to fit in a breadboard.
The module is NOT 5V tolerant so make sure your UART is only 3.3V!
- To program the MCU first connect the UART to the RX, TX and GND pins.
- Hold down RST and press BOOT, release the RST button and then the BOOT button.
- The MCU shall now be in bootloader mode and can be programmed with Arduino

Questions
How big is the ESP32-S2 Devboard PCB?
It measures 31.9 × 44.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32-S2 Devboard use?
21 parts, built around the ESP32-S2-WROOM-N4 and SP6205EM5-L/TR. 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 Devboard KiCad files?
From the laserbenny/ESP32-S2_Devboard repository on GitHub, at the commit this page was made from: the board is ESP32-S2-DevBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-S2 Devboard design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
