It measures 66 × 45.5 mm and has 2 copper layers, 1.6 mm thick.
31 parts, built around the CH340N and AMS1117-3.3. 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 Sidharth-Saji/Protocol_Analyzer repository on GitHub, at the commit this page was made from: the board is Protocol_Analyzer_v1/Protocol_Analyzer_v1.kicad_pcb and its schematic Protocol_Analyzer_v1/Protocol_Analyzer_v1.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 Sidharth-Saji before reusing the design.
