Questions
How big is the SPACEDOS01 PCB?
It measures 93.5 × 48.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SPACEDOS01 use?
92 parts, built around the ATMEGA1284P-AU, BMI-S-204-F, BMI-S-210-F and OPA2314M/TR. 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 SPACEDOS01 KiCad files?
From the UniversalScientificTechnologies/SPACEDOS01 repository on GitHub, at the commit this page was made from: the board is hw/sch_pcb/SPACEDOS01.kicad_pcb and its schematic hw/sch_pcb/SPACEDOS01.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SPACEDOS01 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).
