Questions
How big is the MAXTempTC PCB?
It measures 21.7 × 29.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MAXTempTC use?
30 parts, built around the MAX31856. 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 MAXTempTC KiCad files?
From the Duet3D/TempDaughterboards repository on GitHub, at the commit this page was made from: the board is MAXTempTC/MAXTempTC.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MAXTempTC design in my own project?
Its repository states no licence, so its author keeps all rights: ask Duet3D before reusing the design.
