While i'm unfortunately not a KS backer, but MUCH later, I do have a teensy 3.2 I'm using for a project (one I plan on using the peechy for prototyping mechanics for!). If we want to try and run it on something like that, I'd be willing to give it a go and do testing.

Unrelated question: For those of us who bought using the backerkit store-front post-KS, when can we expect to start seeing shipments? I realize we're behind the backers, but I'm really looking forward to having the peachy! If we start seeing them around the time the last of the backers get theirs, I should be getting ready to prototype the PCBs for my project (I just got most of the stuff talking on my breadboard prototype!). Suffice it to say, I'm really excited!
