Something for the keyboard designer to consider: Using a couple of esp32 wrooms would be cheaper and it would provide bluetooth.
OP, what are the knobs for? Are they for vertical and horizontal scroll? Or are they for an x&y axis knob cursor? Those are super interesting!
Thank you for this list. I just moved from reddit where it has now become full of politics, bots, and toxicity. I miss the narwhal bacon days...
