Questions
How big is the Fraduino PCB?
It measures 59.8 × 96.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Fraduino use?
82 parts, built around the STM32L432KBU6, MAX98357AEWL+T, W25Q32JVSSIQ and SRV05-4. 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 Fraduino KiCad files?
From the XiangYyang/Fraduino repository on GitHub, at the commit this page was made from: the board is pcb/fraduino.kicad_pcb and its schematic pcb/fraduino.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fraduino design in my own project?
Its repository publishes it under the GPL-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).
