The HC-12 Wireless Serial Communication Module is a long-range 433 MHz wireless UART communication module designed for easy wireless data transmission between microcontrollers and electronic devices. It provides a simple serial interface, allowing it to communicate with Arduino, STM32, PIC, and other microcontroller platforms without requiring complex wireless protocols.
The HC-12 operates as a transparent serial data link, meaning data sent through the UART interface can be transmitted wirelessly to another HC-12 module. It supports multiple communication modes and adjustable baud rates, making it suitable for remote-control systems, sensor networks, robotics, industrial monitoring, and DIY wireless projects.
