HC-12 433Mhz SI4463/SI4438 Wireless Serial Port Module

The HC-12, a 433MHz wireless serial port module built on top of the SI4463 or SI4438 RF transceiver, is intended for reliable, long-range communication in embedded and microcontroller systems. Operating in the Ultra High Frequency (UHF) band, it provides dependable wireless data transfer with low interference over up to 1,000 meters in open areas. Applications needing low power consumption and high transmission efficiency are best suited for this module. With its straightforward UART (Universal Asynchronous Receiver/Transmitter) interface, the HC-12 module is simple to integrate with a variety of microcontrollers, such as Arduino, Raspberry Pi, and other development platforms. Various communication modes are supported, such as broadcasting, fixed-point transmission, and transparent transmission, which can be chosen according to the needs of the application.
