M5Stack Atomic DTU LoRaWAN Base EU868 (STM32WLE5CC)
Atom DTU LoRaWAN-EU868 is a LoRaWAN programmable data transmission unit (DTU) designed for the 868 MHz frequency band, specifically tailored for the EU868 band, suitable for Europe and other regions using the EU868 band. This module employs the STM32WLE5 solution, supporting long‑range communication with low power consumption and high sensitivity. The module features a built‑in LoRaWAN protocol stack, supporting Class A, Class B and Class C operation modes for easy connection to various LoRaWAN server platforms such as TTN, ChirpStack, Actility, Tencent Cloud, etc.; it also supports LoRa® point‑to‑point (P2P) communication mode and uses a UART communication interface (controlled via the AT command set) for flexible configuration, and integrates an RS485 communication interface to provide reliable wired connectivity for industrial field devices. The product uses a high‑performance rubber‑duck antenna, with an optimized design to deliver more stable signal coverage and longer communication range, suitable for a variety of complex environments. In LoRaWAN mode, the module can act as a node to connect to a gateway for data collection and management; in P2P mode, it can achieve direct device‑to‑device communication without a gateway. Structurally, the module features a standard 35 mm DIN rail slot at its base, allowing direct installation on industrial rails for quick deployment and maintenance in cabinets or distribution boxes. It is widely used in long‑range, low‑power IoT communication scenarios such as smart agriculture, industrial monitoring, and environmental monitoring node deployments.
