It has a built-in SIM7028 communication module and uses serial communication with an AT command set for easy control. The unit also comes with an SMA external antenna interface, which greatly improves communication quality and signal stability. The SIM7028 module supports most Cat-NB bands, making it widely useable worldwide.\u003c\/p\u003e \u003cp\u003eWhat sets the ATOM DTU series apart from typical DTUs, which usually only offer basic data transmission, is its open construction. With the \u003ca href=\"\/hi\/products\/atoms3-lite-esp32s3-dev-kit\"\u003eATOMS3 LITE controller\u003c\/a\u003e, you can modify programs to meet specific needs. Additionally, the unit provides various connectors such as RS485, I2C, and custom options, allowing you to easily include sensors and actuators. Its rail mounting structure makes it well-suited for embedding in different industrial control settings. The ATOM DTU NB2 is ideal for low-latency, low-throughput projects, including remote control, asset tracking and remote monitoring.\u003c\/p\u003e \u003ch2\u003eFeatures\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eWorks with AtomS3\/AtomS3 Lite\/Atom matrix\/Atom Lite\u003c\/li\u003e \u003cli\u003eGlobal version\/multi-band support\u003c\/li\u003e \u003cli\u003eStrong signal access capability\u003c\/li\u003e \u003cli\u003eAT command control\u003c\/li\u003e \u003cli\u003eSIM card type: Nano\u003c\/li\u003e \u003cli\u003eExternal antenna: SMA antenna\u003c\/li\u003e \u003cli\u003eSerial communication: UART 115200bps\u003c\/li\u003e \u003cli\u003eData transmission (kbps): 127 (DL)\/159 (UL)\u003c\/li\u003e \u003cli\u003eSupports multiple network protocols\u003c\/li\u003e \u003cli\u003eMultiple certifications including radio, environmental, and carrier standards\u003c\/li\u003e \u003cli\u003eMultiple power supply options\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eSpecifications\u003c\/h2\u003e \u003ctable width=\"778\"\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd width=\"215\"\u003eCommunication Module\u003c\/td\u003e \u003ctd width=\"563\"\u003eSIM7028\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eSupported Cat-NB Bands\u003c\/td\u003e \u003ctd\u003eB1\/B2\/B3\/B4\/B5\/B8\/B12\/B13\/B14\/B17\/B18\/B19\/B20\/B25\/B26\/B28\/B66\/B70\/B85\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eNetwork Protocols\u003c\/td\u003e \u003ctd\u003eTCP\/UDP\/HTTP\/TLS*\/DTLS*\/DNS\/NTP\/PING\/LWM2M\/COAP*\/MQTT\/MQTTS\/SSL\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eCarrier Certifications\u003c\/td\u003e \u003ctd\u003eDeutsche Telekom\/Vodafone\/Telefonica\/China Telecom\/China Mobile\/China Unicom\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eCommunication Method\u003c\/td\u003e \u003ctd\u003eUART 115200bps\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eAntenna\u003c\/td\u003e \u003ctd\u003eStick Antenna @2.5dBi total length 110mm SMA inner needle\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd rowspan=\"2\"\u003ePower Supply Methods\u003c\/td\u003e \u003ctd\u003eRS485 Port (HT396 Interface 9-24V)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eUSB 5V\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eGrove Interface Load Capacity\u003c\/td\u003e \u003ctd\u003eDC5V\/0.9A\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eOperating Temperature\u003c\/td\u003e \u003ctd\u003e0-40°C\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eProduct Dimensions\u003c\/td\u003e \u003ctd\u003e65.3 x 28.7 x 24mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003ePackage Dimensions\u003c\/td\u003e \u003ctd\u003e168 x 117 x 19.7mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eProduct Weight\u003c\/td\u003e \u003ctd\u003e24.6g\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003ePackage Weight\u003c\/td\u003e \u003ctd\u003e38.7g\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003ch2\u003eResources\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/docs.m5stack.com\/en\/atom\/Atom%20DTU_NB_IoT2\"\u003eProduct Wiki\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003ePackage Contents\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e1x ATOM DTU2-NB-IOT2 Base\u003c\/li\u003e \u003cli\u003e1x AtomS3 Lite\u003c\/li\u003e \u003cli\u003e1x Stick Antenna (2.5dBi total length 110mm SMA inner needle)\u003c\/li\u003e \u003cli\u003e1x SMA Antenna Red Cap\u003c\/li\u003e \u003cli\u003e1x M2 Hex Wrench\u003c\/li\u003e \u003cli\u003e1x M2 x 16 Screw\u003c\/li\u003e \u003cli\u003e1x HT3.96-4P Terminal\u003c\/li\u003e \u003c\/ul\u003e","brand":"M5Stack","offers":[{"title":"Default Title","offer_id":50847261655313,"sku":"K059-B","price":25.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/6285\/6209\/files\/atom-dtu-nb-iot2-kit-global-version-sim7028-m5stack-k059-b-43043289989315.jpg?v=1735209416","url":"https:\/\/abcd3032.myshopify.com\/hi\/products\/atom-dtu-nb-iot2-kit-global-version-sim7028","provider":"Tayyab Zak","version":"1.0","type":"link"}
