Product Description

RF1100-232 wireless transceiver modules, 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, the linear transmission distance up to 200 meters, can be widely used in the field of wireless data transmission of wireless meter reading, industrial remote control. It is a low-cost 433MHz band wireless permeability of the module.

Features

1. low-power module, the maximum transmit power 10mW
2. Operating voltage 2.7-5.5V DC power supply (recommended operating at 5V)
3. Operating in the 433MHz ISM band, license-exempt use (420MHz to 440MHz)
4. 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
5. Support a transparent data the transmission and DL/645 Statute. Provide 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 wireless meter reading system DL/645 Statute
6. up to 256 programmable channels (20M-band). According to 200KHz interval frequency can provide at least 256 channels to meet the multiple communication combination    mode.
7. 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
8. Professional single-chip module design, reducing user costs
9. 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.
10. 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
11.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.
12.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)
