Questions
How big is the PMOD LEDArray PCB?
It measures 90.5 × 26.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PMOD LEDArray use?
139 parts, built around the GN1640. 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 PMOD LEDArray KiCad files?
From the jjhorton/PMod repository on GitHub, at the commit this page was made from: the board is PMod_LEDArray/Hardware/PMOD_LEDArray.kicad_pcb and its schematic PMod_7Segment/hardware/PMod_7Segement.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PMOD LEDArray design in my own project?
Its repository states no licence, so its author keeps all rights: ask jjhorton before reusing the design.
