Ebyte E77-400M22S STM32WLE5CCU6 433~470MHz 22dBm 5.6Km LoRaWAN Node Wireless Module - UART Interface

Ebyte E77-400M22S STM32WLE5CCU6 433~470MHz 22dBm 5.6Km LoRaWAN Node Wireless Module - UART Interface

E77-400M22S is a standard LoRaWan node module designed and produced by Ebyte, with an operating frequency band of 410~510MHZ, supports LoRaWAN 1.0.3 EU433/CN470 standards, supports CLASS-A/CLASS-C node types, and supports two network access methods: ABP/OTAA. At the same time, the LoRa 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, which is an excellent choice for current IoT applications.
