The M5Stack Atomic DTU LoRaWAN Base EU868 is a compact and powerful data transmission unit for wireless communication over the LoRaWAN network. It utilizes the integrated STM32WLE5 chip with LoRa support to enable particularly energy-efficient and long-range data transmission. With support for LoRaWAN Class A, B, and C, this module is ideal for use in professional IoT applications. Communication occurs via UART using AT commands or alternatively via RS485 – perfect for industrial applications. Thanks to its P2P functionality, the module can also communicate directly with other LoRa devices without the need for a gateway. The included whip antenna provides high range and stable signal quality. Installation is easy via DIN rail, allowing for quick integration into existing control cabinets. Additionally, there are LEGO-compatible mounting options available. The module is compatible with development platforms such as Arduino IDE, UIFlow1, and UIFlow2. Thus, the Atomic DTU is suitable for both industrial applications and smart agriculture projects.
