Questions
How big is the ESPProbe PCB?
It measures 47 × 44 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESPProbe use?
16 parts, built around the MAX31855KASA+T and AM2302. 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 ESPProbe KiCad files?
From the Ehryk/ehryk.github.com repository on GitHub, at the commit this page was made from: the board is Circuits/ESPProbe/ESPProbe.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESPProbe design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ehryk before reusing the design.
