The module adopts the RAK3172-8-SM-I (built-in STM32WLE5) core solution, featuring long transmission range, low power consumption, and high receiving sensitivity. It is specifically designed for the EU868 frequency band, complying with European RF regulations, and is suitable for the EU and regions adopting the EU868 band. The module integrates a complete LoRaWAN protocol stack, supporting three operating modes: Class A/Class B/Class C, and is also compatible with peer-to-peer (P2P) communication. It supports low-power sleep mode to meet the requirements of long-endurance terminals. Hardware-integrated DIP switches allow flexible switching of UART communication pins to adapt to different main control platforms. The module uses standard AT commands for control and supports multi-module stacking for easy function expansion. Equipped with a high-performance rubber duck antenna, it improves signal stability, coverage, and communication distance, adapting to complex industrial and outdoor environments. This module can act as a collection node connected to a LoRaWAN gateway for data acquisition and remote management; it can also implement direct device-to-device communication in P2P mode without a gateway. Typical applications include smart agriculture, industrial monitoring, environmental monitoring, and other long-range low-power IoT communication scenarios.
