315Mhz RF Wireless Transmitter and Receiver module Kit
Description:
The kit consists of a transmitter and a receiver, very popular for remote control.They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link.
Putting an antenna on either the RX or/and TX will further extend the range.
Solder a wire of length about 17.3cm to both transmitter and receiver into the antenna hole. This wire is your antenna.
