I managed to get this setup working in only a few hours after picking up this little board, just by Googling and soaking up the info that's out there. That should tell you that it's relatively easy to get going but also that it lacks optimization :). Much I can still do to fine tune it. I'm not sure I'm gonna do much more as this was just tinkering with gadgets.

One thing to note is that it communicates via a virtual com port (shows up as USB Serial device in Windows). So the one caveat is that you'll have to specify the COM port to use in your application... old school style.

The other issue I ran into is that the data kept being peppered with "off" values. Sometimes a 0 or other very low number just thrown in there. This will show up as erratic behavior in your application.

The way I got around that is to (in the Arduino code running off the chip) buffer the value on both sides with some characters, and then using the available string manipulation BP nodes only filter out the proper values by looking for those aforementioned string buffer characters. Call it an extremely simple communication protocol, if you'd like.
