WS8452BHS is a LoRa wireless data transmission module designed and produced by Silent-Smart,it supports the 230MHz power band and has a maximum transmission power of 30dBm.
Adopting ASR's first domestically produced SoC chip supporting LoRa LPWAN wireless communication protocol
Low frequency band, with better obstacle diffraction ability compared to frequency bands such as 433/470/868/918
Its Lora core adopts the new generation SX1262 design scheme, with longer transmission distance, faster speed, and smaller size
Supporting fixed-point transmission, transparent transmission, wireless wake-up, and wireless relay functions, its high-performance MCU greatly improves functionality and efficiency
The internal data processing adopts a 3-level cache, greatly increasing the stability and real-time performance of the data.
Support 230Mhz power frequency band
Adopt LoRa spread spectrum technology, with strong anti-interference performance and long communication distance
Support users to set communication keys by themselves, and cannot be read, which greatly improves the confidentiality of user data
Support maximum 1W (about 30dBm) transmission power
Support AT command configuration module
Support Modbus programmable register read and write operations, and can flexibly customize product functions
Support air wake-up, that is, ultra-low power consumption function, suitable for battery-powered applications
Support transparent transmission, fixed-point transmission, broadcast transmission, channel monitoring, wireless relay and other function
Support deep sleep, the power consumption of the whole machine is about 2uA in this mode
Support 0.3k~15.6kbps data transmission rate
Industrial standard design, support long-term use at -40~+85℃
Antenna interface two choices, U.LF connector or stamp hole
