Questions
How big is the Temp sensor PCB?
It measures 52.5 × 52.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Temp sensor use?
40 parts, built around the ATMEGA328P-AU, TJA1051T and LM1117-5.0. 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 sensor KiCad files?
From the Zwackelmann/brewbot repository on GitHub, at the commit this page was made from: the board is pcb/temp-sensor/temp-sensor.kicad_pcb and its schematic pcb/can-atmega-02-layout/can-atmega-02-layout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Temp sensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask Zwackelmann before reusing the design.
