feather-eyespi

A plus-size FeatherWing base board that accepts an Adafruit Feather and breaks out an EYESPI connector for eInk and TFT displays.

Working with a lot of eInk and TFT displays means constantly re-wiring the EYESPI cable. This adapter cuts out that step — plug the Feather in, plug the display in, done. Single-sided board with minimal routing to keep assembly straightforward.
