Questions
How big is the Ac Temp Control V2 PCB?
It measures 44.9 × 39.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ac Temp Control V2 use?
20 parts, built around the ATMEGA328-PU, DHT11, CAT24C256LI and L7805. 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 Ac Temp Control V2 KiCad files?
From the datandleorg/climate_control repository on GitHub, at the commit this page was made from: the board is circuit/Ac Temp Control V2.kicad_pcb and its schematic Ac Temp Control/Ac Temp Control .kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ac Temp Control V2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask datandleorg before reusing the design.
