It measures 68.6 × 49.5 mm and has 2 copper layers, 1.6 mm thick.
23 parts, built around the MAX3232ID and LM2596S-5.0. 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 avnguyen08/Blutooth_Serial repository on GitHub, at the commit this page was made from: the board is Hardware/Blutooth_Serial.kicad_pcb and its schematic Hardware/Blutooth_Serial.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 avnguyen08 before reusing the design.
