Hi All, I'm new here..
Long time listener, First time caller..

Wile waiting quietly for my Polargraph SD vitamin kit to arrive I have been toying around with the Polargraph Server firmware on an Arduino with a adafruit motor shield.. (The only stepper I have are to small to do much with..they where from an old project)

Long story short I didnt have a USB cable long enough and 2.4Ghz Xbee's muck with my mouse/keyboard...

Soooo I had a pair of 3DR Radio 433Mhz radios sitting on my desk,
Turns out they work! Best think is their header is standard FTDI-style pinout! fully programable blah blah blah...

Im not affiliated with 3DR at all, just thought they might come in handy for someone that needs a long range link
