This is a really neat idea for a macro keyboard. If it supported staggered rows and row heights, not to mention structural rigidity it would be good for everyday use too.

Is there a mouse module? Can you connect in a "staggered" manner rather than in a linear grid?

This is awesome!

How does the rigidity of the keyboard hold up with many keys and what's the cost of the materials at higher order quantity?

A while back I was frustrated when wanting to buy a keyboard that there were no triangle-shaped keyboards or circle-shaped keyboards. This lack of peculiar keyboard shapes gave me the idea to make a keyboard that could be reconfigurable into any shape my heart desired. I’m still working on the firmware and making more keys but I wanted to share my progress so far. Heres the source if anyone’s interested in how I made it: https://github.com/notaroomba/keybytes

I looked over the PCB and schematic and it looks well polished. Not a first draft obviously.

I sort of don’t get the 4x I2C busses. I’m probably missing something obvious but it isn’t immediately apparent how the units all have addressing worked out.

I’ve wondered when someone would do this (which gets rid of the annoyances of scanning).

The real breakthrough would be reprogrammable key legends in something like e-ink.

This is very cool.

It needs spacers / extensions so it can be laid out as desired.

Very cool, would really like one

this is extremely cool. would love to see full board

Now give them all wheels so they can rearrange themselves on my desk
