ESP32 E-Ink Development Board https://github.com/mike-rankin/ESP_trINKet This design was a test run using an E-Ink display. It can be powered off of a battery or USB cable. When both a battery and USB cable are plugged in, it will charge the battery. The latest board revision has swapped several ESP32 pins around to make it compatible with the gxEPD library. The programmer board is located at: https://github.com/mike-rankin/ESP32_Programmer I would like to extend special thanks to Drew at OSH Park for providing the PCB and Jean-Marc Zingg for his library. The project started using the Waveshare library, which was difficult to use. The gxEPD library is much better. The Sleep test code currently performs a hardware test to verify that the display, sensors, and ESP32 are functioning properly. If you can create something of your own, I would love to see it by contacting me at @mikerankin.
