The 42 most common of 43 parts.
It measures 113 × 49 mm and has 2 copper layers, 1.6 mm thick.
43 parts, built around the ATMEGA328P-AU, T835-800B, CNY17-3 and MC7805CT. 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 CatoLynx/TH8200Control repository on GitHub, at the commit this page was made from: the board is Hardware/TH8200Control.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask CatoLynx before reusing the design.
