Questions
How big is the NeoPLC PCB?
It measures 75 × 110 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NeoPLC use?
39 parts, built around the STM32G071CBT6, TLP291-4, AP2112K-3.3 and ISL3178EIBZ. 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 NeoPLC KiCad files?
From the ukaratas/NeoPLC repository on GitHub, at the commit this page was made from: the board is NeoPLC.kicad_pcb and its schematic NeoPLC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NeoPLC design in my own project?
Its repository states no licence, so its author keeps all rights: ask ukaratas before reusing the design.
