This LoRaWAN-EU868 is a communication module based on LoRa technology, specifically designed for the EU868 frequency band, making it ideal for Europe and regions using the same frequency standard. The STM32WLE5 core gives the module long-range communication, low power consumption, and high sensitivity.
It comes with the LoRaWAN protocol stack and supports three operating modes: Class A, Class B, and Class C. It also supports point-to-point (P2P) communication, allowing flexible data transmission even without a central gateway. Configuration is done through a UART connection using simple AT commands, making setup straightforward and adaptable to different needs.
Equipped with a rubber antenna, it provides stable signal coverage and an extended communication range, even in difficult areas. It can function as a data collection node, sending information to a gateway for centralised management, or it can enable direct communication between devices when no gateway is available.
