HC-12 SI4463 433MHz 1000 m Transceiver + Antenna - Arduino Radio Module
This wireless module operates at 433 MHz with a range of up to 1000 meters. It is supplied with voltage from 3.2V to 5.5V.
The modules receive and send two-way UART TX, RX communication, which makes sending and receiving data very simple. There is no need to build data packages, encode and send on your own as is the case with other communication modules, just enter data and send, the module will do the "package", encode and send it, the same is the case of reading data.
By connecting the module to Arduino using a simple UART interface, the module becomes easy to use. This small module has fast data transmission of up to 236,000 bps.
Thanks to this module, you can send information from one Arduino to another over long distances, which will be useful, for example, when designing an inspection vehicle or other projects.
Product features
The module has the "SET" function, thanks to which you can, among other things:
change transmit - receive speed
change transmit power
change broadcasting channel
change frequency
activate so-called "SLEEP" function, in which the module consumes 22μA only.
HC-12 is in charge of wireless serial and SI4463 transceiver for radio communication.
The board has an external u.FL antenna socket and a soldering pad for antenna included in the set.
