I wanted to do a couple e-paper projects and wanted them to be a little cleaner than just wiring a few modules together so I figured I would just make a driver board myself to fit my project better.

I borrowed heavily from the schematic for the ESP32 driver board that Waveshare makes for e-paper displays. (https://www.waveshare.com/wiki/E-Paper_ESP32_Driver_Board)

For one of my e-paper projects I also took some inspiration from this project:
https://github.com/lmarzen/esp32-weather-epd

The code this person wrote for their project is awesome too and it really simplified things for me as I just picked out pieces from it that I needed.  So thanks to that person! :)


No doubt there's some other idea I picked up from various places so thanks for those folks too!

So after lots of reading up on all that I finally knocked together a board to drive these displays that suited what I Was going for.

I wanted to design a circuit board that I could stick to the back of the display with some double sided tape with the PCB extending past the edge of the display that would then support the display by slotting into a base.  The idea being the whole screen/pcb assembly would be self contained and just merely resting in the slot of the base.

Amazingly it worked right out of the gate :)

In the pictures I didn't have a battery connected but I currently have one stuck to that board with double sided tape.  There's plenty of room for the 4000mAh 3.7V LiPo that I use!


The display pictured here is a 3 Color, 800x480 panel.
