An EInk, ESP32-based Game Boy

This is very impressive. The battery life on this must be insane.

Honestly surprised nobody has tried this before. I would prefer a dedicated control setup but this is cool too.

I also have interest in knowing the battery life on this. My main thought is that e-ink screens only consume batteries while refreshing the screen, how does it look like refreshing it 30/60 times a second. As a big fan of e-ink i would love to own a retro handheld with this tech.
