Purecrea HC-12 SI4438 433MHz radio module UART

The HC-12 SI4438 offers you an easy way to establish serial communication over 433MHz radio. This allows you to exchange data between Arduinos or send it to a Raspberry Pi. The HC-12 is a reliable radio module with a very high range of up to 1000m outdoors. The module can be configured using AT commands. The configuration of the module is retained even after power off and is not lost. To switch to AT mode, pin 5 "SET" must be connected to GND.
