Questions
How big is the MOBO SMD PCB?
It measures 90.2 × 48.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MOBO SMD use?
64 parts, built around the STM32F415RGT6, 24LC256-I/P and LD29080DT33R. 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 MOBO SMD KiCad files?
From the lkesteloot/alice repository on GitHub, at the commit this page was made from: the board is alice3/kicad/MOBO_SMD/MOBO_SMD.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MOBO SMD design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
