It measures 59.1 × 78.1 mm and has 2 copper layers, 1.6 mm thick.
28 parts, built around the AT89C4051-24PU and BS170. 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 domokos/LRChanger repository on GitHub, at the commit this page was made from: the board is MFG/kicadchanger/lrchanger.kicad_pcb and its schematic MFG/kicadchanger/lrchanger.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 domokos before reusing the design.
