Questions
How big is the Pcb ledmatrix PCB?
It measures 216 × 89 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pcb ledmatrix use?
302 parts, built around the 74AHCT125D, ESP32-C3-WROOM-02-H4, SPX3819M5-L-3-3 and USBLC6-2SC6. 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 Pcb ledmatrix KiCad files?
From the stebit/pcb-ledmatrix repository on GitHub, at the commit this page was made from: the board is pcb/pcb-ledmatrix.kicad_pcb and its schematic pcb/led_array.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcb ledmatrix design in my own project?
Its repository states no licence, so its author keeps all rights: ask stebit before reusing the design.
