When I clicked on that Teensy link I got a "Not Found" message, but this one seems to work. (The URL was terminated with .htm but should have been .html in this particular case.)

Another advantage to using the Teensy (if it has sufficient ROM) would be the built-in micro USB connector which could serve dual use as both the firmware flashing port and emulator interface. Has anyone looked into using a Teensy 3.1 in low power applications? I haven't looked into this myself.
