Questions

How big is the Purrtico TLA PCB?

It measures 100 × 50 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Purrtico TLA use?

77 parts, built around the OPA1679ID. 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 Purrtico TLA KiCad files?

From the greyboxaudio/Purrtico-TLA repository on GitHub, at the commit this page was made from: the board is Purrtico_TLA/Purrtico_TLA.kicad_pcb and its schematic Purrtico_TLA/Purrtico_TLA.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Purrtico TLA design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
