I'm looking for fairly solid clock accuracy (serial comms) so maybe going with the USB 32 bit Whacker is a slightly better choice with what looks to be a clock module on board. I do like that the Microstick would give me a few chip options to try, but I'm concerned that all of them would have to run off of internal clocks. Any thoughts?
