Questions
How big is the T962upgrade PCB?
It measures 63.5 × 63.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the T962upgrade use?
87 parts, built around the CH340C, MAX31850KATB+T and DS18S20. 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 T962upgrade KiCad files?
From the SG-O/T962upgrade repository on GitHub, at the commit this page was made from: the board is T962upgrade.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the T962upgrade design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
