Questions
What parts does the TT Clone AY AT use?
60 parts, built around the ATMEGA644-20AU, MCP1702-5002E/MB, SRV05-4 and TL431A. 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 TT Clone AY AT KiCad files?
From the Upcycle-Electronics/AVR-Transistor-Tester repository on GitHub, at the commit this page was made from: the board is AY-AT Proto Mod 644/TT-Clone-AY-AT.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TT Clone AY AT design in my own project?
Its repository states no licence, so its author keeps all rights: ask Upcycle-Electronics before reusing the design.
