Questions
How big is the BUDDY v1.0.0 PCB?
It measures 115 × 70 mm and has 6 copper layers, 1.6 mm thick.
What parts does the BUDDY v1.0.0 use?
369 parts, built around the TMC2209-LA, BLM18KG121TN1D, BAV99W and BAT54KFILM. 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 MX-RESEARCH/MX_Buddy_Board repository on GitHub, at the commit this page was made from: the board is BUDDY_v1.0.0.kicad_pcb and its schematic BUDDY_v1.0.0.kicad_sch. 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 states no licence, so its author keeps all rights: ask MX-RESEARCH before reusing the design.
