The M301 series gateway module is a high-performance transceiver with integrated radio frequency module. It adopts LoRa remote modulation and demodulation technology and supports LoRaWAN standard protocol and LoRa private protocol. The module adopts Semtech SX1301 and SX1255/SX1257 main chips, which are very suitable for the design of various IoT gateway transceivers. The module supports (G)FSK and LoRa modes, and can simultaneously receive up to 8 LoRa data packets with different spreading factors simultaneously. The module provides SPI and GPIOs interfaces, which are suitable for users to develop quickly.
