大功率前端LoRaWAN网关模块 LoRaWAN1302

LoRaWAN1302是思为无线研发的一款大功率、小体积和SPI接口的LoRaWAN网关前端模块。该模块采用sx1302， SX1250芯片方案，基于Semtech官网标准设计。内置TCXO晶振，支持433/470/868/915MHz各种频段，也可以定制其他特定频率。
LoRaWAN1302设计为收发双天线，将发射天线和接收天线分开。该LoRaWAN网关模块设计为1.5W的输出功率，嵌入式小体积设计，带温度传感器，在无线远程传输控制等行业得以广泛地应用。
LoRaWAN1302产品严格使用无铅工艺生产和测试，均符合RoHS和Reach的标准。
