Communication Modules
GPMLx93x Series LoRaWAN Modules
The GreenPalm GPMLx93x Series LoRaWAN Modules are based on the SX1302 digital baseband chip. They use the Mini PCIe mechanical form factor and provide an SPI interface.
The modules can be used in LoRaWAN gateways and proprietary LoRa network gateways, as well as for developing LoRa network analysis tools and studying proprietary networks. Compared with the previous generation, the SX1302 offers lower power consumption, higher data throughput and lower cost.
