RF Serial 434 Mhz Module HC-11 (1-40M)

RF Serial 434 Mhz Module HC-11 (1-40M)

RF Serial 434 Mhz Module HC-11 (1-40M)

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 realise 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 the communication. Please also note that this module do not work with the 433 Mhz Serial RF Transmitter Module HC-12.
