Description

Atom DTU LoRaWAN868 is a programmable data transmission unit (DTU) suitable for the 868MHz frequency LoRaWAN. The module adopts the ASR6501 solution, supporting long-distance communication while featuring ultra-low power consumption and high sensitivity. The module integrates the LoRaWAN protocol stack and uses a serial communication interface (controlled by AT commands). It can be used as a collection node to connect to gateways for data collection and management. The integrated SMA external antenna interface enhances communication quality and signal stability. Unlike general DTUs that only have data transmission functions, the Atom DTU LoRaWAN868 series adopts a more open architecture design. The Atom-Lite controller can modify the program according to actual business needs, and the whole machine reserves multiple interfaces (RS485, I2C, custom interfaces) for user expansion, facilitating the rapid access of sensors and actuators. It comes with a rail clamping structure, perfectly embedding into various industrial control sites. A cost-effective solution for small data collection nodes.
