Questions
How big is the Base PCB?
It measures 67.2 × 107.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Base use?
34 parts, built around the LM2596S-5.0, AMS1117 and ULN2803A. 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 Base KiCad files?
From the akshaim/OpenPLC-Internship repository on GitHub, at the commit this page was made from: the board is Hardware/Baseboard/base.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Base design in my own project?
Its repository states no licence, so its author keeps all rights: ask akshaim before reusing the design.
