Product Overview
The HC-11 Wireless RF Module is a compact and reliable long-range serial communication module operating in the 433MHz frequency band. Based on the CC1101 transceiver chip, it enables transparent wireless UART communication between microcontrollers.
Unlike short-range modules, the HC-11 provides extended communication distance, making it ideal for industrial control, remote monitoring, and wireless sensor networks. It is easy to integrate using standard serial communication (TX/RX), requiring minimal configuration.
