Cat-NB frequency bands. It features a built-in SIM7028 communication module, uses serial communication (controlled via AT commands), and integrates an SMA external antenna interface, significantly improving communication quality and signal stability. The SIM7028 module covers most Cat-NB frequency bands, ensuring global applicability. Unlike general DTUs that only support data passthrough, the Atom DTU series adopts a more open architecture design. The AtomS3-Lite controller allows users to modify the program according to actual business needs, and the device provides multiple interfaces (RS485, I2C, custom interfaces) for user expansion, facilitating quick integration of sensors and actuators. The built-in rail clamping structure allows it to be seamlessly embedded into various industrial control environments. \u003cstrong\u003eAtom DTU NBIoT2\u003c\/strong\u003e is ideal for low-latency, low-throughput applications such as remote control, asset tracking, remote monitoring, telemedicine, and shared bikes.\u003c\/p\u003e\n\u003ch2 data-id=\"Features\" id=\"features\"\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCompatible with AtomS3\/AtomS3-Lite\/Atom-Matrix\/Atom-Lite\u003c\/li\u003e\n\u003cli\u003eGlobal version\/multi-band support\u003c\/li\u003e\n\u003cli\u003eStrong signal access capability\u003c\/li\u003e\n\u003cli\u003eAT command control\u003c\/li\u003e\n\u003cli\u003eSIM card type: Micro SIM\u003c\/li\u003e\n\u003cli\u003eExternal antenna: SMA antenna\u003c\/li\u003e\n\u003cli\u003eSerial communication: UART 115200bps\u003c\/li\u003e\n\u003cli\u003eData transmission (kbps): 127 (DL)\/159 (UL)\u003c\/li\u003e\n\u003cli\u003eSupports multiple network protocols\u003c\/li\u003e\n\u003cli\u003eMultiple certifications for radio, environmental, and carrier standards\u003c\/li\u003e\n\u003cli\u003eMultiple power supply methods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-id=\"Includes\" id=\"includes\"\u003eIncludes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x AtomS3-Lite\u003c\/li\u003e\n\u003cli\u003e1 x Atom DTU NBIoT2\u003c\/li\u003e\n\u003cli\u003e1 x Rubber antenna (2.5dBi, total length 110mm, SMA inner pin)\u003c\/li\u003e\n\u003cli\u003e1 x SMA antenna red cap\u003c\/li\u003e\n\u003cli\u003e1 x M2 hex wrench\u003c\/li\u003e\n\u003cli\u003e1 x M2x16 screw\u003c\/li\u003e\n\u003cli\u003e1 x HT3.96-4P terminal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-id=\"Applications\" id=\"applications\"\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAsset tracking\u003c\/li\u003e\n\u003cli\u003eRemote monitoring\/control\u003c\/li\u003e\n\u003cli\u003eShared bikes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-id=\"Specifications\" id=\"specifications\"\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv class=\"table-container\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eParameters\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication module\u003c\/td\u003e\n\u003ctd\u003eSIM7028\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported Cat-NB bands\u003c\/td\u003e\n\u003ctd\u003eB1\/B2\/B3\/B4\/B5\/B8\/B12\/B13\/B14\/B17\/B18\/B19\/B20\/B25\/B26\/B28\/B66\/B70\/B85\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNetwork protocols\u003c\/td\u003e\n\u003ctd\u003eTCP\/UDP\/HTTP\/TLS*\/DTLS*\/DNS\/NTP\/PING\/LWM2M\/COAP*\/MQTT\/MQTTS\/SSL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCarrier certifications\u003c\/td\u003e\n\u003ctd\u003eDeutsche Telekom\/Vodafone\/Telefonica\/China Telecom\/China Mobile\/China Unicom\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication method\u003c\/td\u003e\n\u003ctd\u003eUART 115200bps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAntenna\u003c\/td\u003e\n\u003ctd\u003eRubber antenna @2.5dBi, total length 110mm, SMA inner pin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower supply methods\u003c\/td\u003e\n\u003ctd\u003eRS485 port (HT396 interface 9-24V)\u003cbr\u003eUSB 5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGrove interface load capacity\u003c\/td\u003e\n\u003ctd\u003eDC 5V\/0.9A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating temperature\u003c\/td\u003e\n\u003ctd\u003e0 ~ 40°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Size\u003c\/td\u003e\n\u003ctd\u003e65.3 x 28.7 x 24mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct weight\u003c\/td\u003e\n\u003ctd\u003e24.6g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Size\u003c\/td\u003e\n\u003ctd\u003e168 x 117 x 19.7mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGross weight\u003c\/td\u003e\n\u003ctd\u003e38.7g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eLearn and Documents\u003c\/h2\u003e\n\n  → DOCUMENTS\n\n\u003c\/div\u003e","brand":"m5stack-store","offers":[{"title":"Default Title","offer_id":46036118929468,"sku":"jne1787247183221","price":21.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0676\/6985\/2220\/files\/atom-dtu-nb-iot2-kit-global-version-sim7028_1.webp?v=1787247191","url":"https:\/\/www.mossheath.com\/products\/atom-dtu-nb-iot2-kit-global-version-sim7028","provider":"My Store","version":"1.0","type":"link"}
