M5Stack AtomDTU Programmable Rail Data Transmission Unit LoRaWAN868MhzRS485 Communication Module

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 Product FeaturesASR6501Operating frequency 868MHzSerial communication UART 115200bps AT command With super anti interference ability able to work normally in complex interference environmentRS485 communication interface with 12V input interface internal integrated DCDC step down 5V Modbus Master s
