Questions
How big is the BUDDY v1.0.0 PCB?
It measures 105 × 70 mm and has 6 copper layers, 1.6 mm thick.
What parts does the BUDDY v1.0.0 use?
364 parts, built around the TMC2209-LA, DT1140-04LP, BLM18KG121TN1D and BAV99W. 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 BUDDY v1.0.0 KiCad files?
From the bobc/Prusa-Mini-assembly repository on GitHub, at the commit this page was made from: the board is Prusa3d/Buddy-board-MINI-PCB/rev.1.0.0/BUDDY_v1.0.0.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BUDDY v1.0.0 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
