ATOM DTU NB CN is a programmable data transmission unit (DTU) with integrated NB-IoT communication function. The built-in SIM7020C module covers most of the Cat-NB frequency bands and integrates the SMA external antenna interface to improve the communication quality and signal stability of the device. Unlike the DTU, which generally only has the function of data transparent transmission, the ATOM DTU series adopts a more open architecture design. The controller ATOM LITE can modify the program at will according to the actual business, and the whole machine reserves a variety of interfaces (RS485, I2C, custom interfaces) for user expansion, which is convenient for the rapid access of sensors and actuators. The self-contained guide rail clamping structure is perfectly embedded in various industrial control sites. ATOM DTU NB CN is very suitable for various low-latency, low-throughput application scenarios (such as remote control, asset tracking, remote monitoring, remote medical treatment, shared bicycles, etc.).
