I’ve searched around on here a bit, and it looks like there’s a fair amount of interest in a split ortholinear option (along the lines of the Ergodox or the Corne ). But trying to develop such a thing from scratch for a relatively small market is going to be cost prohibitive.
I propose that instead of building from scratch, it should be possible to just mount 2 macropads in the space where the keyboard would normally be. It seems like this ought to work with some firmware changes and an adapter board that just relocates the connections. Maybe also add a few buttons to the adapter to replicate the thumb clusters.
I figured I’d throw this idea out there for some initial feedback before I sink a bunch of time into trying to make it happen. Does this sound like a plausible idea?
