Designed by KEEBD.
Version of the original dumbpad but with support for an OLED display in place of the LED's and resistors. The EC11 rotary encoder-compatible slots have a non-plated through-punch for their mounting point on each side, which may be flagged as erronious by PCB manufacturers but has no effect on functionality.
