    Project Re: Pololu's Wixel + Arbotix Commander V2

    It's bidirectional via xbee. My data rate from the robot is to send one row of data (12 bytes) every 4s or so. I'm actually doing a single read of a single servo's temperature once per second, and...

    I should also document the 3d-print encapsulated switch wired to one of the push buttons, giving me the ability to set a mode. E.g. TwitchMX's turret mode + laser was toggled in this manner :)
