RF1100-232 wireless transceiver modules, a wireless communication chip using TI's high performance CC1101 free 433 MHz ISM band license-free use, 232/485 serial communication, transparent transmission, simple applications without programming, and great ease of use, provide up to 256 channels, low-power operation, and a linear transmission distance of up to 200 meters, can be widely used in the fields of wireless data transmission, wireless meter reading, and industrial remote control. It is a low-cost 433 MHz band wireless permeability module.

Features:

• low-power module, the maximum transmit power 10mW
• Operating voltage 2.7-5.5V DC power supply (recommended operating at 5V)
• Operating in the 433MHz ISM band, license-exempt use (420 MHz to 440 MHz)
• High anti-interference ability and low error rate, based on the FSK modulation mode, the high-efficiency forward error correction and channel interleaved coded technology to improve the ability of the anti-random interference and burst interference
• Support transparent data transmission and the DL/645 Statute. Provide a transparent data interface, able to adapt to any standard or nonstandard user protocol.Automatically filter out false data generated in the air (the fee that is issued); the communication software to support the wireless meter reading system DL/645 Statute
• up to 256 programmable channels (20 M-band). To meet the multiple communication combination mode, at least 256 channels with a 200 kHz interval frequency can be provided.
• interface for TTL level interface can be directly connected to the microcontroller or serial devices; supporting USB-TTL adapter plate for easy PC debugger, set the parameters and the communication between the PC and the microcontroller 485 level; interface
• Professional single-chip module design, reducing user costs
• large data buffer. Interface baud rate equal to the air baud rate, three kinds of user-selectable baud rate: 4800, 9600, 19200 (interface rate maximum is set to 19200 bps); data format is 8N1/8E1/8O1 user-defined, can be transmitted up to 30 bytes in the data frame, the more flexible and user-programmed.
• Intelligent data control and the user does not need to prepare excessive programs. Even if it is a half-duplex communication, the users do not need to prepare excessive programs, from the interface to transmit / receive data, air / receive hair conversion, control operation, the module automatically
• Variety of antenna options to meet the different needs of the user. Such as springs antenna, a variety of gain rubber antenna, suction cup antenna, etc.
• Communication distance: in linear visual case, the antenna placed a high degree of location> 2 meters, the 9600 bps rate transmission distance up to 200m (200 m between the microcontroller transmission, computer radiation transmitted through the computer, radio frequency interference, distance of about 100-150 meters)
