HF-PA-v10 ;) Is this the end of the search for a 5W Digital PA? HF-PA-v10 is now a rugged 10W PA! We also do 100W+ now ;)

It measures 100 × 98.8 mm and has 2 copper layers, 1.6 mm thick.
16 parts, built around the NE555 and IRF510. 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 Asiderr/prototype repository on GitHub, at the commit this page was made from: the board is back/back.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 Asiderr before reusing the design.
