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.
Schematic
Purchase
Given out through Patreon, but contact me if interested.
Parts
The parts list can be downloaded **HERE**. This can be directly uploaded into Digikey if you'd like.
Assembly
The board hooks up to the trigBoard in the same way as other adapter boards:
Code
Coming soon...
