[Introduction]：E77-900M22S is a standard LoraWan node module developed by Ebyte. It supports LoRaWAN 1.0.4 EU868, US915, AU915, AS923, IN865, KR920, RU864 standards, CLASS-A/CLASS-C node types, and ABP/OTAA network access methods. At the same time, the module has a variety of low-power modes, and the external communication interface uses a standard UART. Users can access the standard LoRaWAN network through simple configuration of AT commands. It is an excellent choice for current IoT applications.
