SRWF-2E80A Spread spectrum wireless communication module

SRWF-2E80A series module is remote wireless communication module for the IOT. The RF chip uses SEMTCH’s unique LoRA spread spectrum technology and has strong anti-interference ability and high sensitivity, which greatly improves data transmission distance; At the same time, the module can also choose to use GFSK modulation which can improve the compatibility of the application module.

Product Information

 Product Brief :

 
SRWF-2E80A series module is  remote wireless communication module for the IOT. The RF chip uses SEMTCH's unique LoRA spread spectrum technology and has strong anti-interference ability and high sensitivity, which greatly improves data transmission distance; At the same time, the module can also choose to use GFSK modulation which can improve the compatibility of the application module.

 

SRWF-2E80A module supports full transparent data transfer protocol, and can adapt to wireless data transmission requirements with any protocol.
The SRWF-2E80A module provides transparent communication modes for two modulation modes: GFSK mode and LoRA mode. Communication modes can be selected by configuration software. At the same time, the module has low power sleep function, sleep current is less than 2uA; the module supports low-power CSMA protocol, module can automatically exit dormancy to listen for air data, automatic sleep after data transmission, the utility model is convenient for various battery powered systems



Application :

SRWF-2E80A series wireless data transmission module is suitable for:
1)
     Automatic meter reading charging system for water supply, gas and heating.

2)     Active RFID tag

3)     Wireless intelligent control of municipal street lamp and lighting.

4)     IOT industrial equipment and meters.

5)     Operation state monitoring of wind turbine generator. 

6)     LED display for fairway buoy and field temporary site. 

7)     Building energy monitoring, wireless sensor network

8)    Intelligent home management system

l
  
SMT&DIP type ,Save space, easy integration

l  Transmitting power software adjustable

Power adjustable range: -1dBm~20dBm, factory default 17dBm (50mW).

l  Multi operating frequency band

Provide 433/470 to 510MHz two frequency band module selection, before purchasing, determine frequency band.

l  High anti-interference and low bit error rate

GFSK/FSKLoRa Modulation Mode 、Efficient FEC channel coding technique, The anti-interference ability of wireless data transmission is improved, and the transmission error rate is reduced.

l  Multi communication channels

Provide software to set Channel mode, there are 16 channels can be choosed
l  Various serial baud rates and data formats
Modules can set serial port baud rate by software as: 1200, 2400, 4800, 9600, 19200bps, factory default baud rate is 9600bps. Serial data format support 8 bit data (8N1, 7E1, 7O1, etc.) format and 9 bit data (8E1, 8O1, 9N1, etc.) format of a variety of combinations, can be set by software. The factory defaults is 9 bit data (8E1, 8O1, 9N1, etc.).

l  Compatible with industrial and civil design

The operating temperature supports -40℃ to 85℃ and is compatible with various industrial and civil different requirements. High integration  and stable communication. Strong anti-interference ability, support the signal strength to read
l
  
Low power sleep mode, suitable for battery powered system

With low power design, the sleep current of the wireless module is less than 3uA.
