A UV-Exposure box for creating home-made PCBs
Digit board is an open-source printed circuit board by Cylindric3D, from the Cylindric3D/uv-box repository on GitHub. It is a 2-layer board of 57.8 × 22.9 mm with 2 parts on 16 nets, routed with 130 tracks and 10 vias.
Note that documentation and schematics are also available as images in the GitHub Pages site for this project.

For creating the PCBs with UV-sensitive boards:

It measures 57.8 × 22.9 mm and has 2 copper layers, 1.6 mm thick.
2 parts. 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 Cylindric3D/uv-box repository on GitHub, at the commit this page was made from: the board is Electronics/digit_board/digit_board.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 Cylindric3D before reusing the design.
