Questions
How big is the Temp Monitor PCB?
It measures 66.9 × 66.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Temp Monitor use?
127 parts, built around the ESP32-S3-WROOM-1-N8, TJA1051T/3/1, ADS1015IDGS and LMR33630CDDA. 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 Monitor KiCad files?
From the Alex-C-EE/Reliable-Temp-Monitor repository on GitHub, at the commit this page was made from: the board is Temp-Monitor/Temp-Monitor.kicad_pcb and its schematic Deliverables/Temp-Monitor/Temp-Monitor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Temp Monitor design in my own project?
Its repository states no licence, so its author keeps all rights: ask Alex-C-EE before reusing the design.
