Questions
How big is the FIAControl PCB?
It measures 150 × 72 mm and has 4 copper layers, 1.6 mm thick.
What parts does the FIAControl use?
110 parts, built around the STM32F413VGT6, 74HCT541D, SPAN02A-03 and LM258ADT. 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 FIAControl KiCad files?
From the CatoLynx/LCD-FIA repository on GitHub, at the commit this page was made from: the board is Hardware/FIAControl/FIAControl.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the FIAControl design in my own project?
Its repository states no licence, so its author keeps all rights: ask CatoLynx before reusing the design.
