Questions
How big is the Tx02 PCB?
It measures 18 × 10 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tx02 use?
13 parts, built around the ATTINY202-SSN, CH340E and TS5A23159DGSR. 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 Tx02 KiCad files?
From the McbeEringi/pcb-stuff repository on GitHub, at the commit this page was made from: the board is proj/avr/tx02/tx02.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tx02 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).
