Involvement:General (knows how to use it) - Ownership:more than 1 month
-Cheap! -Very small and light. Barely noticeable. -Easy to use. Just plug in the included 4 pin female-female cable to the module and the other end to Vcc, Gnd, Tx and Rx on a Arduino, and your'e ready to go. -Simple to connect to the module with a terminal program on a PC or Android cellphone and send control commands(appears as LINVOR with a pin of 1234). -Doesn't require any special programming or code library's to integrate in to your program.
Only one: The lack of reverse polarity protection in the circuit. Be careful not to switch Vcc and Gnd by mistake or it will fry it in an instant! (happened to me....)
Great, cheap and easy solution for your wireless Arduino project. Simple to interface with it, the same way you would use the Arduino IDE's serial monitor to send commands via usb, just wireless.
