Questions
How big is the DisplayController PCB?
It measures 42.7 × 64 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DisplayController use?
32 parts, built around the LM2937IMP-3.3 and LM2937IMP-5.0. 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 DisplayController KiCad files?
From the bwilkins/DisplayControllerPCB repository on GitHub, at the commit this page was made from: the board is DisplayController.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DisplayController design in my own project?
Its repository states no licence, so its author keeps all rights: ask bwilkins before reusing the design.
