102 parts, built around the T31ZX, W25Q32JVSSIQ, AZ1117IH-3.3TRG1 and NX2016SA-24MHZ-EXS00A-CS07553. 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 CapnRon/Teacup repository on GitHub, at the commit this page was made from: the board is TeaCup(C)3.2/12-30-23-Teacup.kicad_pcb-revC.kicad_pcb and its schematic TeaCup(C)3.2/12-30-23-Teacup.kicad_pcb-revC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask CapnRon before reusing the design.
