46 parts, built around the ESP32-C3-MINI-1, LSM6DS3, ME6211C33M5G-N and RV-3028-C7. 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.
From the voidthecryptic/voidthecryptic.github.io repository on GitHub, at the commit this page was made from: the board is files/desai-mochi/Desai_Mochi_V2.kicad_pcb and its schematic files/desai-mochi/Desai_Mochi_V2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
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).
