- This is the KiCAD Projects Repository.
- I recommend not to use these KiCAD data.
- Some projects are unfinished or have issues in the circuit.
- I designed these circuits based on whether I can solder them, not on whether the average person can.

Questions
How big is the ATtiny PCB?
It measures 13.5 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ATtiny use?
11 parts, built around the ATTINY1604-SSF and CH340K. 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 ATtiny KiCad files?
From the Tert2/KiCAD repository on GitHub, at the commit this page was made from: the board is ATtiny/ATtiny.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ATtiny design in my own project?
Its repository states no licence, so its author keeps all rights: ask Tert2 before reusing the design.
