1.Product introduction
The SRWF-2E80B module is a remote wireless communication module for IOT. The RF chip is based on LoRa spread spectrum technology by SEMTCH company and has strong anti-interference ability and high sensitivity, which has greatly improved the transmission distance of data; at the same time, the module can also choose to use GFSK modulation mode, improve the compatibility of the application module. It can support data transmission to LoRaWAN base station and other protocol formats such as Class-A, Class-B, Class-C and so on.
SRWF-2E80B module supports full transparent data transfer protocol, and can adapt to the wireless data transmission requirements of any protocol.
The SRWF-2E80B module provides transparent communication in two modulation modes: the GFSK mode and the LoRA mode. Communication modes can be selected by configuration software. At the same time, the module with low power sleep function, sleep current is less than 2uA; the module supports low-power CSMA protocol. The module can automatically and regularly quit hibernation to listen air data and automatically sleep after data transmission, so that it can be applied to various battery powered systems.
