Programs and CAD files for the LED hex display PCB.
This repository contains several programs to run on an Arduino and drive a display made from LEDs.
The display was made as a small-volume low-cost PCB using a design drawn in KiCad.
CAD files for the schematic and PCB, designed in 2014 using KiCad V3. This version of KiCad is so old now that it's not practical to update the files. At the time of writing, KiCad is at V8.0.5 and uses a completely different set of PCB footprints from V3. So although it's possible to update the schematic files to use the latest format and the latest symbols, it's difficult to map those symbols to the new…
