Questions
How big is the MDotBuddy PCB?
It measures 36 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MDotBuddy use?
23 parts, built around the FT230XS-R, MIC5504-3.3YM5, TTL-232R-3V3 and USBLC6-2SC6. 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 MDotBuddy KiCad files?
From the idpromnut/mDotBuddy repository on GitHub, at the commit this page was made from: the board is mDotBuddy.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MDotBuddy design in my own project?
Its repository states no licence, so its author keeps all rights: ask idpromnut before reusing the design.
