2.4Ghz RF Transmitter and Receiver TTL Pair Communication Module, 2 Pieces

Kit Contain 2X 2.4Ghz Communication Module, Distance = 50 Meter Line of Sight Baud Rate = 9600 When interfacing with Arduino, these modules can be powered by connecting the 5V and GND pins between Arduino and the RF module chip. The remaining two pins are TX (transmit) and RX (receive). The connections for these are by the opposite, as in, the TX pin of one is connected to the RX pin of the other. Now, after all these connections are made, data can be transferred serially through Arduino which will be transferred wirelessly through the RF module. The working can be seen by doing the above connections and connecting the Master and Slave module to the laptop, run Arduino IDE and open Serial Monitor. Make sure both of them are working at the same Baud Rate. 4 Channel Works like chatting on Hyperterminal, no need of Carriage Return. Working Voltage = 5V Working Frequency = 2.4GHz
