Questions
How big is the Display Controller PCB?
It measures 45 × 59 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Display Controller use?
46 parts, built around the ESP32-WROOM-32E, TCA9406DCUR and FMB2222A. 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 Display Controller KiCad files?
From the Ir0nC0wb0y/Split-Flap repository on GitHub, at the commit this page was made from: the board is Electronics/SF_Master-Controller/Display Controller.kicad_pcb and its schematic Electronics/SF_Digit-Controller/SF-DC_HE-BREAKOUT.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Display Controller design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
