The Electronic Paper Display Adapter Board

Introduction

The TrigBoard is all about low power, but typically displays are not, so if you need a display project to run off batteries, electronic paper is a perfect fit... note that these displays are not meant to show animations or anything like that. Just simple static text/images that update at some slow interval rate. So for example, the trigBoard will automatically wake up once an hour to check its own battery voltage. This is a perfect time for it to update a screen with some data like, Bitcoin prices, YouTube stats, weather, etc... Oh yea, and since the power management circuitry on trigBoard will actually kill the 3.3V supply, that means the display also looses power, but these displays will keep their image even with no power! So now we have a <1uA display system.
