Questions
How big is the Temp-1w8-pro PCB?
It measures 40 × 65 mm and has 2 copper layers, 0.8 mm thick.
What parts does the Temp-1w8-pro use?
66 parts, built around the PJ-242. 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 Temp-1w8-pro KiCad files?
From the makerspacelt/temp-1w8-pro repository on GitHub, at the commit this page was made from: the board is project/project.kicad_pcb and its schematic project/project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Temp-1w8-pro design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
