Questions
How big is the Dadboard PCB?
It measures 397 × 165 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dadboard use?
350 parts, built around the ATMEGA32U4-AU and PRTR5V0U2X. 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 Dadboard KiCad files?
From the lfgberg/dadboard-pcb repository on GitHub, at the commit this page was made from: the board is KiCad/dadboard.kicad_pcb and its schematic KiCad/dadboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dadboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask lfgberg before reusing the design.
