Questions
How big is the Incubator PCB?
It measures 49 × 43 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Incubator use?
17 parts, built around the ATMEGA8A-AU, DHT11, 1N4148WT and BC547. 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 Incubator KiCad files?
From the Sanjay-083/PCB_design repository on GitHub, at the commit this page was made from: the board is incubator/incubator.kicad_pcb and its schematic Boost_converter/Boost_converter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Incubator design in my own project?
Its repository states no licence, so its author keeps all rights: ask Sanjay-083 before reusing the design.
