Description
Overview
GAOTek Lora GWM V2 module is a LoRa gateway RF module designed based on the SX 1302 Chip. It adopts the standard Mini PCI-e package, SPI interface, the module has External PA and LNA, Transmit Power up to 27dBm, and the half-duplex design is convenient for users to quickly develop LoRa gateway equipment. SX1302 is a new generation LoRa gateway baseband chip launched by us. It is equipped with front-end sx1250 and can support spreading factors SF 5 to SF 12. Compared with the previous generation SX1301 gateway solution, it can support higher-speed data communication, while the power consumption is greatly reduced, the design is simplified, and the performance is significantly improved.
