This is HC-11 CC1101 433MHz Wireless Transceiver RF Serial UART Module. The serial RF module is a low cost, high-performance transparent FSK transceiver with operating at 434 MHz. It features small size, high output power, high sensitivity, long transmission distance, and high communication data rate with auto set up for communication change and data receiving and transmission control.

With the UART interface, it is easy to realize the wireless data transmission with only providing the UART data. It is flexible for the users to set the UART baud rate, frequency, output power, data rate, frequency deviation, receiving bandwidth etc parameters. This module can not work individually, at least 2 pcs would be needed to create communication. Please also note that this module does not work with the 433 Mhz Serial RF Transmitter Module HC-12.

Features :

  1. The frequency band is 434M
  2. Multiple types of serial port transparent transmission modes have respective features, and the mode is changed by command
  3. Absolutely easy to use
  4. Low current consumption; the idle current is 80μA, 3.5mA or 22mA, depending on the selected mode
  5. All functions and parameters are changed by command and can be saved in case of power failure
