Please check the new version: HC-12 44382A 433MHZ High Power Wireless Transceiver Arduino

The HC-12 is a robust, semi-duplex 433MHz wireless serial data transceiver module based on the Si4463 chip. It is designed to provide reliable, long-distance wireless communication, offering an effective alternative to Bluetooth or short-range RF modules. The HC-12 features built-in microcontrollers and configurable parameters, allowing it to communicate transparently with microcontrollers like Arduino or ESP32 using a standard UART serial interface. Its high power output and sensitivity make it ideal for remote control, data logging, and long-range IoT applications.
