WS8454FLS is a LoRa serial module
supporting multiple frequency bands, designed and manufactured by
Chengdu Silent Smart Technology Co.Ltd.
Developed by the STM32WLE5x series SoC chip which is launched by ST company.
Longer transmission distance, faster speed, lower power consumption, and smaller size.
Support fixed-point transmission, transparent transmission, wireless wake-up, wireless relay and other functions.
Internal data processing uses multi-level cache, which greatly increases the stability and real-time of data.
Supports license-free ISM 868MHz band and 915MHz band.
Adopts LoRa spread spectrum technology, which has strong anti-interference performance and long communication distance.
Supports users to set their communication keys, which cannot be read, greatly improving the confidentiality of user data.
Supports up to 158mW (about 22dBm) of transmit power.
Support AT command configuration.
Support Modbus programmable register read/write operation, and flexibility to customize the product function.
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, and the power consumption in this mode is about 1 uA.
Supports data transfer rates from 0.3k to 62.5k bps.
Supports 1.8 ~ 3.6V power supply, 3.3V is recommended.
Industrial standard design, supporting long-term use at -40 ~ + 85 ℃.
