SX1302 LoRa Gateway module
Description This LoRa gateway module with an industrial standard mini PCI expresses form factor is based on the SX1302 chipset. This mPCIe module can be used in any embedded platform offering a free mPCIe slot with SPI connectivity and capable of providing enough power for the module, enabling low-power wide-area communication capabilities to your new gateway design or existing industrial routers/computer. Complete and cost-efficient LoRa gateway solution offering up to eight(8) programmable Lora parallel demodulation channels. Allowing it to receive up to eight LoRa® modulated packets simultaneously. It targets Internet-of-Things (IoT) applications, covering up to 500 nodes per square kilometer in an environment with moderate interference. Features Compliance with LoRaWAN 1.0.2 Multichannel: Eight (8) programmable Lora parallel demodulation channels. mPCIe form factor based on SPI host interface Compact mini PCI express form factor TYP. 50.95*30.0*10.5mm (W*L*H) The voltage of Mini PCI-e is 3.3V, compatible with 3G/LTE mPCIe card TX Power up to 27dBm, Rx sensitivity down to -139dBm@SF12,BW 125kHz.
