Questions
How big is the ULI-05 PCB?
It measures 58 × 39.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ULI-05 use?
55 parts, built around the USBLC6-2SC6, IRF7306TR, SM712 and SS34. 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 ULI-05 KiCad files?
From the kmzbrnoI/uLI-pcb repository on GitHub, at the commit this page was made from: the board is uLI-05/uLI-05.kicad_pcb and its schematic uLI-05/uLI-05.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ULI-05 design in my own project?
Its repository states no licence, so its author keeps all rights: ask kmzbrnoI before reusing the design.
