I just found these on sparkfun:
How the heck do you solder something like that? It's really cheap and a 2.4ghz transceiver should have a lot less interference problems, and the power usage is between the rf transmitters and the transceivers I currently have (RFM12B-S2 Wireless Transceiver - 434MHz - WRL-09582 - SparkFun Electronics)
Does it require anything else to work? The description mentions something about works great with a 16mhz crystal, does it require that though?
