Easiest configuration ever, just shove it on RX/TX pins on Arduino and power it with 5V, also from Arduino, and you are all set! Small form factor, great for embedding applications Range is awesome! I could keep serial communication all around my apartment at 9600bps.
No cons, this is a must buy if you are on Arduino business.
Could came with some specsheet or manual, even though information can be easily found in the internet, just google it.
Definitely recommend this module. If you are looking for a cheap and effective way to integrate wireless serial communication to your arduino project this is the way to go. Buy a couple.
