Questions
How big is the Uprobe-0.1 PCB?
It measures 36 × 77 mm and has 4 copper layers, 1 mm thick.
What parts does the Uprobe-0.1 use?
108 parts, built around the ATMEGA8A-MU, 74LVC2T45DC, AP22653W6 and AMS1117-3.3. 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 Uprobe-0.1 KiCad files?
From the xx0x/uprobe repository on GitHub, at the commit this page was made from: the board is pcb/uprobe-0.1/uprobe-0.1.kicad_pcb and its schematic pcb/uprobe-0.1/uprobe-0.1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Uprobe-0.1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask xx0x before reusing the design.
