YouTuber built 30-frame-per-second grayscale Game Boy, then open sourced it for all e-paper displays

A custom open source E Ink driver that could theoretically let any display do the same thing. YouTuber Bo Made It published a video last week demonstrating what he calls the InkBoy on a tiny ESP32-S3-powered e-paper board.
