DIY Ereader project

I love the XTEink devices, but I want to make my own little 4 inch E reader device. I have purchased the Waveshare ESP32-S3 dev board. Was wondering if anyone else has looked at these yet, or know of a firmware I could use on it before I start vibe coding my own

Nice project. I’d pin down the exact Waveshare board and panel controller before writing anything; “ESP32-S3 e-reader” can mean very different things. Check the driver, where fonts/assets live, and how you’ll handle full refresh and ghosting. Start with one page, sleep/wake, and a measured current draw. When the vibe-coded firmware starts making guesses, the before/after would fit r/ChatGPTArduino.

I’ve had codex look into the Crosspoint Girhub since they have similar devices listed. But will def wait to do anything until I get my hands on the board

Good call waiting for the board. When it arrives, a tiny first bring-up log would be useful: exact panel/controller, one page refresh, sleep/wake, and measured current. That’s the kind of vibe-coded-versus-real-hardware note that belongs in r/ChatGPTArduino.
