The 24 most common of 25 parts.
It measures 100 × 50 mm and has 2 copper layers, 1.6 mm thick.
25 parts, built around the SN74LVCC3245APW and LM1117-3.3. 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 electrified/rc2014-mystorm repository on GitHub, at the commit this page was made from: the board is rc2014-mystorm.kicad_pcb and its schematic rc2014-mystorm.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 electrified before reusing the design.
