From the project

An E-Ink PDA device using the ESP32 S3.

This project is a PDA powered by an ESP32-S3 running a custom OS written in C++ using PlatformIO. This project utilizes an E-Ink and OLED screen in tandem to mitigate the refresh rate restrictions of an E-Ink panel while retaining the aesthetics and benefits of using E-Ink. This project is a work in progress and currently amounts to a simple GUI for navigating between apps, a text (.txt) file editor, and a basic file manager. More applications are planned for the future and a list of TO-DOs can be found below.
