WS8453DLS is a low-cost wireless digital transmission module designed and manufactured by Chengdu Silent Smart Technology to support multiple frequency bands.
It is designed based on Semtech's RF transceiver chip LLCC68 and adopts the new LoRaTM modulation technology, which has lower power density and stronger anti-interference performance than the conventional FSK and GFSK modulation technology, and can further improve the reliability of communication.
WS8453DLS supports fixed-point transmission, transparent transmission, wireless wake-up, wireless relay and other functions.
Low cost LoRa UART module
Supports license-free ISM 433MHz band and 470MHz meter reading band.
Adopts LoRa spread spectrum technology, featuring strong anti-interference performance and long communication distance.
Supports users to set their own communication keys, which cannot be read, greatly improving the confidentiality of user data.
Supports a maximum of 158mW (about 22dBm) transmit power
Support AT command configuration module
Support 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.
Support deep sleep, the power consumption of the whole machine in this mode is about 1uA.
Support 2.4k～62.5kbps data transmission rate.
Supports 2.5~5.5V power supply.
Industrial-grade standard design, support -40 ~ +85 ℃ long time use
