Upgraded from the previous generation, it mainly adds an IO expansion chip to enable control of the communication module power enable and software reset, which helps reduce power consumption and ensures that the SIM module can be reset without power cycling when abnormal conditions occur. At the same time, an ADC monitoring circuit has been added, supporting real-time acquisition of the input power voltage from the HT3.96-4P interface to enable power status monitoring. This unit integrates the SIM7028 communication module and uses UART communication (controlled via AT command set). It features an SMA external antenna interface, providing good communication quality and signal stability. The SIM7028 module supports multiple Cat-NB frequency bands and can be used worldwide. Compared with conventional DTUs that only support data transparent transmission, the Atom DTU series adopts a more open architecture design. Multiple interfaces (RS485, I2C \/ custom Grove interface) are reserved for user expansion, facilitating rapid connection of sensors and actuators. The built-in DIN rail mounting structure allows installation in various industrial control environments, making it suitable for low-latency, low-throughput scenarios such as remote control, asset tracking, remote monitoring, telemedicine, and shared bicycles.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"Atom DTU NBIoT2 v1.1\" style=\"width: 80%;
