Wireless RF Kit 433 Mhz (Transmitter+Receiver) v-grrove bearing ULN2803 8-Channel Darlington Sink DriverThe kit is consisted of transmitter and 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. The tiny copper wire (spiral) on the unit is an inductor, not an antenna. Solder a wire of length about 17. 3cm to both transmitter and receiver into the antenna hole. This wire
