LoRa Radio Module - 433MHz Category_Sensors/Input Quadruple relay moduleLoRa Radio Module is a type of long range low data rate data radio modem based on Sx1276 from Semtech. It is a low cost sub 1 GHz transceiver module designed for operations in the unlicensed ISM (Industrial Scientific Medical) and LPRD bands. Frequency spectrum modulation demodulation, multi channel operation, high bandwidth efficiency and anti blocking performance make LoRa modules easy to realize the robust and reliable wireless link. The module can
