Questions
How big is the Blobbadge PCB?
It measures 40 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Blobbadge use?
85 parts, built around the PY32F002AW15U6TR and SMTSOM215BTR. 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 Blobbadge KiCad files?
From the rough-rat/blobbadge repository on GitHub, at the commit this page was made from: the board is blobbadge.kicad_pcb and its schematic blobbadge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Blobbadge design in my own project?
Its repository states no licence, so its author keeps all rights: ask rough-rat before reusing the design.
