Description
Description Atom DTU NBIoT2 is a programmable wireless data transmission unit (DTU) suitable for global Cat-NB frequency bands. It features a built-in SIM7028 communication module, uses serial communication (controlled via AT commands), and integrates an SMA external antenna interface, significantly improving communication quality and signal stability. The SIM7028 module covers most Cat-NB frequency bands, ensuring global applicability. Unlike general DTUs that only support data passthrough, the Atom DTU series adopts a more open architecture design. The AtomS3-Lite controller allows users to modify the program according to actual business needs, and the device provides multiple interfaces (RS485, I2C, custom interfaces) for user expansion, facilitating quick integration of sensors and actuators. The built-in rail clamping structure allows it to be seamlessly embedded into various industrial control environments. Atom DTU NBIoT2 is ideal for low-latency, low-throughput applications such as remote control, asset tracking, remote monitoring, telemedicine, and shared bikes.
