Questions
How big is the Led sign controller PCB?
It measures 160 × 110 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Led sign controller use?
38 parts, built around the ESP32-S3-WROOM-1-N8 and SN74LVC8T245PW. 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 Led sign controller KiCad files?
From the bornhack/led-sign-controller repository on GitHub, at the commit this page was made from: the board is led_sign_controller.kicad_pcb and its schematic esp32-s3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Led sign controller design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
