M5Stack AtomDTU Data Transmission Unit NB-IOT ESP32 RS485 Graphical Programming Guide Rail Type Module

Description ATOM DTU NB is a programmable data transmission unit DTU that integrates NB IoT communication functions The built in SIM7020G 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 interface for users to expand 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 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 Product Features SIM7020G Global version Multi band supportRS485 communication interface with 12V input interface internal integrated DCDC step down 5V Modbus Master slaveStrong signal access capabilityAT command controlSIM card type MicroSIMExternal antenna SMA antenna interfaceGrove expansion interface I2C x1Custom x1Serial communication UART 115200bpsSelf contained rail clampingCat NB frequency band B1 B2 B3 B4 B5 B8 B12 B13 B17 B18 B19 B20 B25 B26 B28
