WS8474HLS is a wireless module designed based on Semtech's SX1281. The module provides ultra-long-distance communication in the 2.4GHz ISM band, and its linearity can withstand severe interference. The module supports Lora, FLRC and (G)FSK modulation modes, with a transmit power of up to 13dBm and a receiving sensitivity as low as -132dBm.
WS8474HLS supports fixed-point transmission, transparent transmission, wireless wake-up, wireless relay and other functions
Supports the global license-free ISM 2.4GHz frequency band
Adopts LoRa spread spectrum technology, with strong anti-interference performance and long communication distance
Supports users to set communication keys by themselves, and cannot be read, which greatly improves the confidentiality of user data
Supports a maximum transmission power of 20mW (about 13dBm)
Supports AT command configuration module
Supports modbus programmable register read and write operations, and can flexibly customize product functions
Supports air wake-up, that is, ultra-low power consumption function, suitable for battery-powered applications
Supports transparent transmission, fixed-point transmission, broadcast transmission, channel monitoring, wireless relay and other functions
Supports deep sleep, the power consumption of the whole machine in this mode is about 3uA
Supports data transmission rate of 1.5k~200kbps
Supports 2.5~5.5V power supply
Industrial standard design, supports long-term use at -40~+85℃
Antenna support: IPEX+PCB, 28.7 * 17.5mm ultra-small size
