Questions
How big is the Dactyl rp2040-right PCB?
It measures 43.4 × 53 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dactyl rp2040-right use?
40 parts, built around the RP2040, SN74LV1T34DBV, W25Q128JVSIQ and 918-318K2023S40000. 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 Dactyl rp2040-right KiCad files?
From the ThomasBoom89/dactyl-pcb repository on GitHub, at the commit this page was made from: the board is dactyl-rp2040-right/dactyl-rp2040-right.kicad_pcb and its schematic dactyl-rp2040-left/dactyl-rp2040-left.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dactyl rp2040-right design in my own project?
Its repository publishes it under the EUPL-1.2 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
