Has anyone attempted using these? I was wondering how hard it would be to use them with the arduino bootloader for my as-yet-not-started RC system project (I will get round to it soon, hopefully). The Zigduino seems to use them, and they've supplied a library to operate the in-built radio. I'm just wondering whether I'd have to be careful with PCB layout etc. to avoid interference.
