Sometimes you just want the smallest Arduino-like thing you can find. This is the case as far as I can tell, with a SAMD21 processor. But for me it turned out to be useless because the boot sequence means it takes a second or two after powering on for your code to run. ATTiny85 turned out to be my answer.
