Introduction
The E77-400/900M22S series are standard LoRaWAN node modules. The E77-400M22S operates in the 410~510MHz band, and the E77-900M22S operates in the 868~930MHz band. The E77-400M22S supports LoRaWAN 1.0.3 EU433/CN470 standards, while the E77-900M22S supports LoRaWAN 1.0.4 EU868/US915/AU915/AS923/IN865/KR920/RU864 standards. Both support CLASS-A/CLASS-C node types and ABP/OTAA network access methods. The modules also feature multiple low-power modes. External communication is via standard UART. Users can easily configure and connect to a standard LoRaWAN network through AT commands. An ideal choice for IoT applications.
