The 47 most common of 52 parts.
It measures 99.9 × 51.4 mm and has 2 copper layers, 1.6 mm thick.
52 parts, built around the BSS138, BSS83P, MMBT3904 and MMBT3906. 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 GadgetReboot/AVR_Programmer repository on GitHub, at the commit this page was made from: the board is KiCAD/GR_AVR_Programmer.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 GadgetReboot before reusing the design.
