Questions
How big is the Marbles v70 PCB?
It measures 88.9 × 106 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Marbles v70 use?
208 parts, built around the STM32F405RGT6, LM324PW, OPA4171AID and R-78E3.3-0.5. 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 Marbles v70 KiCad files?
From the mort13/clandestine_circuitry repository on GitHub, at the commit this page was made from: the board is marbles/hardware_design/pcb/KiCad/marbles_v70.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Marbles v70 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
