Jarek Lupinski created a Teensy 3.x shield for e-paper displays:

Teensy E-Paper Adapter Board

E-Paper is not a simple display to drive. With manual temperature compensation, onboard power regulation requiring external capacitors, and setting up a step-up circuit, there are many factors to consider when working with this display, with the large benefit of not requiring any power to maintain its image once written.

I have created the simplest possible circuit necessary to drive the Pervasive Displays E2215CS062 , available from your favorite distributor. Certain parts from the reference design were substituted with US-available equivalents with assistance from the Pervasive Displays engineering team.

Capacitive touch with Teensy

The Teensy 3 and Teensy LC have several pins that can be used as capacitive touch inputs.  I designed this board in KiCad to experiment with cap touch buttons:

I used the CAPSENSE_CIRCLE component and footprint from the Wickerlib KiCad library to create the cap touch buttons:capsense-combo
