high-performance ATGM336H navigation module from CASIC, using the AT6668 chipset, paired with an active external antenna to provide more accurate and reliable satellite positioning services. Compared to previous products, the AT6668 supports multi-frequency and multi-mode GNSS signal reception, capable of receiving signals from multiple satellite navigation systems (including GPS, BD2, BD3, GLONASS, GALILEO, and QZSS), supporting multi-system joint positioning and single-system independent positioning, with stronger anti-interference capabilities and higher positioning accuracy. In areas with weak signals, it can quickly obtain higher precision location information. This module is suitable for high-precision positioning applications such as vehicle positioning and navigation, IoT positioning devices, etc.\u003c\/p\u003e\n\u003ch2 data-id=\"Features\" id=\"features\"\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSupports multiple satellite navigation systems (GPS\/QZSS\/BD2\/BD3\/GAL\/GLO)\u003c\/li\u003e\n\u003cli\u003eMulti-frequency and multi-system reception\u003c\/li\u003e\n\u003cli\u003eMulti-channel\u003c\/li\u003e\n\u003cli\u003eExternal active antenna\u003c\/li\u003e\n\u003cli\u003e2 x LEGO-compatible holes\u003c\/li\u003e\n\u003cli\u003eProgramming platforms: Arduino, UIFlow, ESP-IDF, etc.\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 Unit GPS SMA\u003c\/li\u003e\n\u003cli\u003e1 x HY2.0-4P Grove cable (20cm)\u003c\/li\u003e\n\u003cli\u003e1 x Active external antenna\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-id=\"Applications\" id=\"applications\"\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eVehicle positioning and navigation\u003c\/li\u003e\n\u003cli\u003eWearable devices\u003c\/li\u003e\n\u003cli\u003eIoT positioning devices\u003c\/li\u003e\n\u003cli\u003eDrones\u003c\/li\u003e\n\u003cli\u003ePortable devices\u003c\/li\u003e\n\u003cli\u003eBus stop announcements\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\u003eParameter\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSoC\u003c\/td\u003e\n\u003ctd\u003eAT6668\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported Satellite Systems\u003c\/td\u003e\n\u003ctd\u003eGPS\/QZSS\/BD2\/BD3\/GAL\/GLO\u003cbr\u003eFrequencies:\u003cbr\u003eBDS：B1I+B1C \u003cbr\u003eGPS\/QZSS\/SBAS：L1 \u003cbr\u003eGALILEO：E1 \u003cbr\u003eGLONASS：R1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannels\u003c\/td\u003e\n\u003ctd\u003e50 channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication\u003c\/td\u003e\n\u003ctd\u003eUART communication, default 115200bps@8N1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePositioning Accuracy\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;1.5m (CEP50)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePositioning Update Rate\u003c\/td\u003e\n\u003ctd\u003eUp to 10Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtocol\u003c\/td\u003e\n\u003ctd\u003eNMEA0183 4.1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensitivity\u003c\/td\u003e\n\u003ctd\u003eTracking: -162dBm, Acquisition: -160dBm, Cold Start: -148dBm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStart Time\u003c\/td\u003e\n\u003ctd\u003eCold Start: 23 seconds, Hot Start: 1 second\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAntenna\u003c\/td\u003e\n\u003ctd\u003eSMA active external antenna (internal screw, internal pin), Gain: 30DBI, Frequency: 1555MHz~1580MHz, Length: 1m, Size: 38 x 36 x 13mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eStandby: DC 5V\/31.64mA \u003cbr\u003eOperating: DC 5V\/40.90mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Size\u003c\/td\u003e\n\u003ctd\u003e71.4 x 24.0 x 8.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Weight\u003c\/td\u003e\n\u003ctd\u003e47.3g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Size\u003c\/td\u003e\n\u003ctd\u003e170.0 x 120.0 x 9.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGross Weight\u003c\/td\u003e\n\u003ctd\u003e53.6g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eLearn and Documents\u003c\/h2\u003e\n → DOCUMENTS \n\u003c\/div\u003e","brand":"m5stack-store","offers":[{"title":"Default Title","offer_id":46036116439100,"sku":"teb1787247161488","price":7.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0676\/6985\/2220\/files\/gpsbds-unit-with-sma-antenna-at6668_1.webp?v=1787247169","url":"https:\/\/luxecladstore.shop\/products\/gpsbds-unit-with-sma-antenna-at6668","provider":"My Store","version":"1.0","type":"link"}
