The ATOM DTU NB2 is a wireless data transmission unit (DTU) designed for NB-IoT projects across global Cat-NB bands. It has a built-in SIM7028 communication module and uses serial communication with an AT command set for easy control. The unit also comes with an SMA external antenna interface, which greatly improves communication quality and signal stability. The SIM7028 module supports most Cat-NB bands, making it widely useable worldwide.
What sets the ATOM DTU series apart from typical DTUs, which usually only offer basic data transmission, is its open construction. With the ATOMS3 LITE controller, you can modify programs to meet specific needs. Additionally, the unit provides various connectors such as RS485, I2C, and custom options, allowing you to easily include sensors and actuators. Its rail mounting structure makes it well-suited for embedding in different industrial control settings. The ATOM DTU NB2 is ideal for low-latency, low-throughput projects, including remote control, asset tracking and remote monitoring.
