HC 12 433Mhz SI4463 Wireless Serial Module

HC 12 433Mhz SI4463 Wireless Serial Module 

The HC-12 433MHz Wireless Serial Module is a long-range, low-power transparent wireless communication module based on the Silicon Labs SI4463 RF chip. It works as a wireless serial port, meaning whatever data is sent to the UART input of one module is wirelessly transmitted and appears at the UART output of the other module.

Operating in the 433MHz ISM band, the HC-12 offers long communication range, good anti-interference performance, and low power consumption, making it ideal for wireless data transmission, remote control, telemetry, and IoT applications.

It is extremely easy to use with Arduino, ESP32, STM32, Raspberry Pi, and other microcontrollers since no RF protocol coding is required.
