RF TRANSMITTER 433MHZ high power FS1000A

Wireless Transmitter Modules allow your Arduino to wirelessly comunicate with other arduinos, or with radio frequency (RF) controlled devices that operate in the same frequency (433Mhz in this case). They work in pairs, meaning you need both a receiver and a transmitter to comunicate with each other. The receiver has 4 pins, but we actually use 3 of them: GND (Ground), VCC (5V) and one DATA pin.
