Seekink-E-paper-HAT-for-Rpi

This a HAT for a epaper display for SEEKINK displays with raspberry pi Also can be used with any oher MCU using the 9 in connector. It supports multiple Displays of almost every Size

Parts

  • Raspberry Pi Zero 2 W
  • 3.7 inch Epaper Display

Plan

I needed a HAT that could be used with a Cheap Epaper dispaly paired with a raspberry pi. I found one on LCSC but it didnt have a HAT of that wa 100% compatible with it. So, i took reference from existing HATs and the Datasheet of the Epaper Display and made my own that could be attatched on top of raspberry pi WH. I also added a 9 pin connector and a Voltage Level shifter so that i can connect it to most of the microcontrollers.s.

It can be programmed using the GxEPD2 Library
