Questions
How big is the VCOMLCD PCB?
It measures 80 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VCOMLCD use?
71 parts, built around the ESP32-WROOM-32, TLV61046ADBV, 74LVC4245AD and XC6220B331MR. 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 VCOMLCD KiCad files?
From the cr1tbit/LCD-thing repository on GitHub, at the commit this page was made from: the board is VCOMLCD.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the VCOMLCD design in my own project?
Its repository states no licence, so its author keeps all rights: ask cr1tbit before reusing the design.
