Questions
How big is the Front display PCB?
It measures 201.9 × 54.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Front display use?
61 parts, built around the ATMEGA88A-AU, ESP-12E, LM2596S-5.0 and LM1117-3.3. 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 Front display KiCad files?
From the slomkowski/octoglow repository on GitHub, at the commit this page was made from: the board is pcb/front-display/front-display.kicad_pcb and its schematic pcb/clock-display/clock-display.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Front display design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
