Questions
How big is the SmartGate3 PCB?
It measures 151 × 77.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SmartGate3 use?
34 parts, built around the MMBT3904. 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 SmartGate3 KiCad files?
From the georf/smartgate-software repository on GitHub, at the commit this page was made from: the board is SmartGate3/SmartGate3.kicad_pcb and its schematic SmartGate3/SmartGate3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SmartGate3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask georf before reusing the design.
