77 open source boards in Displays & LEDs
OLED, LCD and e-paper drivers, LED matrices, addressable LEDs and nixie clocks. Every board here is a public GitHub project with its KiCad files, read for size, layers and parts. Pick one close to your design and simulate its firmware on HardLabs before you build it.
