RF Transmitter Module + RF Receiver Module with 433 MHz Operating Frequency - EXRFTM

RF Transmitter Module + RF Receiver Module is a kit consisting of a wireless transmitter and receiver operating at a frequency of 433MHz.

RF Transmitter XD-FST – Radio transmitter operating with amplitude modulation. Allows data transmission at speeds up to 10Kbps over the widely used 433MHz frequency. Power supply and communication with the transmitter are provided via a pin header with a 2.54mm pitch. The pins on the header are: VCC, GND and DATA. The board also has an additional ANT terminal, to which an antenna can be connected to increase the transmission range of the XD-FST. A transmission range of up to 200 meters is achievable when an antenna is added and the supply voltage is 12V.

RF Receiver XD-RF-5V – Radio receiver operating at a frequency of 433MHz. Allows data reception at speeds up to 10Kbps. Power supply and communication with the receiver are provided via a pin header with a 2.54mm pitch. The pins on the header are: VCC, GND and DATA. The board also has an additional ANT terminal, to which an antenna can be connected to increase the reception range of the XD-RF-5V.

Example connection of XD-FST and XD-RF-5V modules:

The figure shows the connection of the modules XD-FST and XD-RF-5V to a microcontroller of the Arduino type. With the help of a suitable library from github, simple code can be created for wireless connection of a transmitter and receiver kit at 433MHz.
