Is it possible to make Seed Signer work on this module??
Dang, nostr:npub16cpe069rjz6pm5t42xcyhcn66f5rr04k64df3g03fk2wctlrlhsqycedcd looks like I bought the wrong ePaper display.
I figured out the pin mapping, but even though it seems to have the same specs as the version with the Pico mount, just getting garble written to the display.
Here's the display I got:

Any ideas on what might need tweaking?

Maybe eventually. But ePaper isn't a great display for an interactive UI. The screen refresh rate according to the specs is 3s, though I assume that partial updates (only repainting part of the screen) is faster.
ePaper makes more sense for use cases where the display is mostly static (e.g. Kohl's started using them as updatable price displays; doesn't matter if it takes 3-5s to write an update when it's once a week or whatever). Also because they consume zero power while static.
