WS8452DLS is a LoRa wireless data transmission module designed and manufactured by Chengdu Silent Smart Technology, which supports multiple frequency bands.
Developed with the first domestic LoRa-supporting LPWAN wireless communication protocol SoC chip from ASR.
Supports fixed-point transmission, transparent transmission, wireless wake-up, wireless relay function, and its high-performance MCU makes a substantial improvement in function and efficiency.
Internal data processing adopts 3-level cache, which greatly increases data stability and real-time performance.
Support ISM 868 / 915MHz frequency band.
Adopts LoRa spread spectrum technology, which has strong anti-interference performance and long communication distance.
Supports users to set their own communication key, and can not be read, greatly improving the confidentiality of user data.
Supports a maximum of 1W (about 30dBm) transmit power.
Support AT command configuration module
Supports Modbus programmable register read/write operation, which can be flexibly customized.
Supports Wake-on-Air, i.e. ultra-low power consumption, suitable for battery-powered applications
Support transparent transmission, fixed-point transmission, broadcast transmission, channel monitoring, wireless relay and other functions.
