Description

ATOM DTU LoRaWAN868 is a LoRaWAN Programmable Data Transmission Unit (DTU) suitable for 868MHz frequency. The module adopts the ASR6501 scheme, which supports long-distance communication and has both ultra-low power consumption and high sensitivity. The module integrates the LoRaWAN protocol stack and adopts a serial communication interface (using AT command set for control). When used, it can be used as a collection node to access a large number of gateways for data collection and management. Integrate 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. The whole machine reserves a variety of interfaces (RS485, I2C, custom interface) for user expansion, which is convenient for the rapid access of sensors and actuators. With its own guide rail clamping structure, it is perfectly embedded in various industrial control sites. A cost-effective solution for small data collection nodes.
