Questions
How big is the Unocart PCB?
It measures 57 × 71 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Unocart use?
29 parts, built around the LM1117-3.3. 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 Unocart KiCad files?
From the pebucz/unocart4atari repository on GitHub, at the commit this page was made from: the board is unocart.kicad_pcb and its schematic unocart.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Unocart design in my own project?
Its repository states no licence, so its author keeps all rights: ask pebucz before reusing the design.
