Questions
How big is the ATTBootloader PCB?
It measures 24.1 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ATTBootloader use?
7 parts, built around the ATTINY85-20PU. 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 ATTBootloader KiCad files?
From the eBernalZ/attb repository on GitHub, at the commit this page was made from: the board is ATTBootloader.kicad_pcb and its schematic ATTBootloader.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ATTBootloader design in my own project?
Its repository states no licence, so its author keeps all rights: ask eBernalZ before reusing the design.
