Questions
How big is the Generic node PCB?
It measures 48.9 × 17.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Generic node use?
47 parts, built around the ATMEGA328PB-MN, TD1465, 74LVC1G57GM and TJA1051TK/3/1. 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 Generic node KiCad files?
From the lucanastasio/myHomeAutomation repository on GitHub, at the commit this page was made from: the board is hardware/generic_node/generic_node.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Generic node design in my own project?
Its repository states no licence, so its author keeps all rights: ask lucanastasio before reusing the design.
