The 59 most common of 61 parts.
It measures 146.5 × 162.3 mm and has 2 copper layers, 1.6 mm thick.
61 parts, built around the ESP32-WROOM-32, FT231XS-R and UMH3NFHATN. 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 Hak4Kidz/H4K-cryptex repository on GitHub, at the commit this page was made from: the board is hardware/Kicad Files/Hak4Kidz2019.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
