The 159 most common of 228 parts.
It measures 285 × 236 mm and has 6 copper layers, 1.6 mm thick.
228 parts, built around the 74HC240D, 74HC244D, 74HC245D and 74HC367D. 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 psomashekar/Development-Documentation repository on GitHub, at the commit this page was made from: the board is Toaplan2/Raizing/RA9704/ra9704-kicad/ra9704.kicad_pcb and its schematic Toaplan2/Raizing/RA9704/ra9704-kicad/audio-amplifier.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 psomashekar before reusing the design.
