On paper it looks like just about the perfect foot controller platform, and would solve a bunch of little inconveniences in my setup (on top of needing a second foot controller, which is the main thing) and looks like it would be a pretty straightforward, affordable build.
First time I am seeing this but I just ordered one of the supported dev boards and will let you know how it goes once I get it built. Looks really good as far as interface, programming and flexibility.
on the back there are also TRS jacks that allow some of the switches to also control analog synths. There is also a toggle switch on the back that adapts the foot-switch midi behavior to be either on-off toggles or triggers
