Questions
How big is the MTR C3 TempHum PCB?
It measures 90.8 × 25.5 mm and has 4 copper layers, 1.59 mm thick.
What parts does the MTR C3 TempHum use?
79 parts, built around the BH1750FVI-TR, BME680, RT9080-33GJ5 and AO3401A. 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 MTR C3 TempHum KiCad files?
From the MoreThanRobotsFR/MTR_C3_TempHum repository on GitHub, at the commit this page was made from: the board is Hardware/MTR_C3_TempHum/MTR_C3_TempHum.kicad_pcb and its schematic Hardware/MTR_C3_TempHum/MTR_C3_TempHum.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MTR C3 TempHum 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).
