Questions
How big is the ESP S2 SoM HW00 PCB?
It measures 26.3 × 27.6 mm and has 6 copper layers, 0.85 mm thick.
What parts does the ESP S2 SoM HW00 use?
58 parts, built around the ESP32-S2FH4, MIC5528-3.3YMT-T5, 2450AT18A100E and DF40C-60DP-0.4V(51). 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 S2 SoM HW00 KiCad files?
From the PumaFPV/PSoM repository on GitHub, at the commit this page was made from: the board is Hardware/PSoM_ESP32_S2/ESP_S2_SoM_00/ESP_S2_SoM_HW00.kicad_pcb and its schematic Hardware/PSoM_Carrier/PSoM_Carrier_00/PSoM_Carrier_00.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP S2 SoM HW00 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
