Using an E-Paper Display with your KNX IoT DevBoard

This document will help you connect a supported e-paper display to your KNX IoT DevBoard.

Requirements

If the E-Paper specific interface is soldered on

The Devboard has conveniently-placed pins on the side, to make for an easy connection with the E-Paper display. However, the header is not soldered on by default. If you’re able to solder a header on, then connect the E-Paper display as shown in the image below. NOTE: The pin mapping is highlighted by the use of colored rectangles surrounding the corresponding pins.

If the E-Paper specific interface is not soldered on

Otherwise, you can still connect the E-Paper display, because all the required pins are made available elsewhere on the board. However, the end-result won’t look as neat. In any case, please refer to the image below for how the connections are made.
