Heyuan new wireless 433MHz LoRa transmitter receiver data transmission modules, Model No.IOT-L2S-B1M/S are designed and manufactured based on the LLCC68 LoRa RF chip from Semtech.
The master module can be connected with the gateway via the RS485 port. The slave module can be connected with the sensors or meters via the RS485 port, and it can also work as an end node and repeater simultaneously. The work mode can be set through the configuration tool. To meet the application needs of different customers, users can form a networking transmission without blind spots and distance limitations by combining multiple modules.
