Product description: LoRaWAN EU868 MHz module with antenna - Unit expansion module - M5Stack U184-EU868
The LoRaWAN Unit EU868 module is an advanced communication extension dedicated to IoT systems, based on the energy-saving STM32WLE5 microcontroller . It supports the European 868 MHz band and offers full compliance with the LoRaWAN 1.0.3 protocol (Class A, B, C), as well as point-to-point (P2P) communication mode. Thanks to very high reception sensitivity (up to -137 dBm) and the included stub antenna with a gain of 2.8 dBi , it ensures a stable transmission range even in difficult conditions. Communication with the module takes place via UART using AT commands. Small dimensions and compatibility with the LEGO system facilitate assembly in mobile and educational projects.
