Questions
How big is the Massue bento v4 PCB?
It measures 142 × 23 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Massue bento v4 use?
101 parts, built around the SN74LVC2T45DCU, MIC2876-5.0YMT-TR, AT42QT1070-MMH and FT230XQ-R. 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.
Where can I download the Massue bento v4 KiCad files?
From the benkuper/BenTo-Legacy repository on GitHub, at the commit this page was made from: the board is hardware/massue_bento_v4.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Massue bento v4 design in my own project?
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).
