HC-12 SI4438 433MHz Radio Module UART
The HC-12 SI4438 offers you a simple way to realize a serial communication via 433MHz radio. Thus, you can exchange data between Arduinos or even send it to a Raspberry Pi. The HC-12 is a reliable radio module and has a very high range of up to 1000m outdoors. The module can be configured using AT commands. The module's configuration is retained even after power off and is not lost. To switch the module to AT mode, pin 5 "SET" must be connected to GND.
