Questions
How big is the Ardiu usb PCB?
It measures 76.2 × 25.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ardiu usb use?
58 parts, built around the ATMEGA32U4-AU, BMP280, AO4838 and RB551V-40. 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 Ardiu usb KiCad files?
From the LithosphereRocketry/ardiu-pcb repository on GitHub, at the commit this page was made from: the board is ardiu-usb/ardiu-usb.kicad_pcb and its schematic ardiu-mini/ardiu-mini.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ardiu usb design in my own project?
Its repository states no licence, so its author keeps all rights: ask LithosphereRocketry before reusing the design.
