Ensure the top face (ceramic antenna side) faces the sky with no metallic shielding directly above it for optimal satellite signal acquisition. \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/2_05_cfe4fb3a-7606-45ab-bbbd-633535869298.jpg?v=1789543740\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/2_06_ed1abf2d-8506-4204-8506-d19026e6276e.jpg?v=1789543759\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/2_07_6b10a65a-32cc-4022-8cb5-c4895cdd4ac3.jpg?v=1789543772\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/2_08_c7f447e4-e8b2-4a8c-b576-e8a680743914.jpg?v=1789543786\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/2_09_2a25a0d5-cfb3-4f65-9162-be3e8630bc1a.jpg?v=1789543800\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/2_10_2a7379bb-4532-47c4-91ea-aafe94de38b2.jpg?v=1789543810\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch2\u003ePractical Application Scenarios\u003c\/h2\u003e\n\u003ch3\u003e1. Fleet Telematics and 4G Cellular Integration\u003c\/h3\u003e\n\u003cp\u003eWhen paired with an Ebyte 4G DTU or cellular modem, the E108-GN04Q acts as the core spatial data engine. It feeds real-time NMEA4.11 coordinate data over UART to the DTU, which then pushes the payload to a cloud server via MQTT or TCP\/IP. This enables high-precision logistics tracking, vehicle speed monitoring, and geofencing for commercial fleet management.\u003c\/p\u003e\n\u003ch3\u003e2. Unmanned Aerial Vehicle (UAV) Flight Control Systems\u003c\/h3\u003e\n\u003cp\u003eGiven the strict payload limits of drones, the lightweight footprint (starting at 20.0 x 22.0 mm) of the E108 series is highly advantageous. By leveraging the multi-constellation support (BDS\/GPS\/GLONASS\/GALILEO), UAV flight controllers can calculate highly accurate 3D spatial positioning and velocity metrics, reducing hover drift and ensuring reliable return-to-home automation.\u003c\/p\u003e\n\u003ch3\u003e3. Industrial IoT Personnel Safety Wearables\u003c\/h3\u003e\n\u003cp\u003eFor construction or mining personnel tracking, the module’s low power consumption allows integration into battery-operated smart helmets or vests. The wide 2.7-5.5V voltage tolerance seamlessly accommodates Li-ion or Li-Po battery discharging curves without needing complex step-up\/down regulators, guaranteeing continuous geographic reporting.\u003c\/p\u003e\n\u003ch3\u003e4. Precision Agriculture and Autonomous Farming Equipment\u003c\/h3\u003e\n\u003cp\u003eWhen integrated with Ebyte LoRa modules or serial servers, the E108-GN04Q2 can be deployed on automated tractors or agricultural field sensors.

What is the fundamental difference between the E108-GN04Q and E108-GN04Q2 modules?\u003c\/h3\u003e\n\u003cp\u003eThe core chipset, electrical parameters, communication interfaces (UART), and supported protocols (NMEA4.11, UBX) are identical across both models. The only difference is the physical dimension: the E108-GN04Q measures 20.0\u003ci\u003e22.0\u003c\/i\u003e7.8mm, while the E108-GN04Q2 measures 25.0\u003ci\u003e25.0\u003c\/i\u003e8.0mm, accommodating different PCB layout requirements and ceramic antenna sizes.\u003c\/p\u003e\n\u003ch3\u003e2. Do I need to design external RF matching circuits for the antenna?\u003c\/h3\u003e\n\u003cp\u003eNo. Both modules come pre-equipped with an integrated ceramic antenna. This highly integrated design eliminates the need for complex external RF impedance matching, reducing bill of materials (BOM) costs and simplifying the hardware design cycle.\u003c\/p\u003e\n\u003ch3\u003e3. How do I configure the module and parse the GNSS data on my host MCU?\u003c\/h3\u003e\n\u003cp\u003eThe modules communicate via a standard UART interface supporting NMEA4.11 and UBX protocols. You can connect it directly to your MCU's UART port to receive standard NMEA sentences (such as $GPGGA,$GPRMC) which contain longitude, latitude, time, and fix status. No proprietary SDK is mandatory for basic data parsing.\u003c\/p\u003e\n\u003ch3\u003e4. Is this module a direct replacement for other mainstream GNSS modules in legacy systems?\u003c\/h3\u003e\n\u003cp\u003eYes. Both the E108-GN04Q and E108-GN04Q2 are explicitly designed with software and hardware interface compatibility matching other major GNSS module manufacturers. This ensures integrators can execute a drop-in replacement with minimal PCB revisions or firmware overhauls.\u003c\/p\u003e","brand":"Ebyte Official Store - IoT Module Manufacturer","offers":[{"title":"E108-GN04Q","offer_id":48826565722317,"sku":"E108-GN04Q","price":10.67,"currency_code":"USD","in_stock":true},{"title":"E108-GN04Q+SH1.0mm","offer_id":48826565755085,"sku":"E108-GN04Q+SH1.0mm","price":0.0,"currency_code":"USD","in_stock":false},{"title":"E108-GN04Q2","offer_id":48826565787853,"sku":"E108-GN04Q2","price":10.67,"currency_code":"USD","in_stock":true},{"title":"E108-GN04Q2+SH1.0mm","offer_id":48826565820621,"sku":"E108-GN04Q2+SH1.0mm","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/E108-GN04Q.jpg?v=1789542828","url":"https:\/\/ebyteiot.com\/it\/products\/ebyte-e108-gn04q-q2-multi-mode-gnss-module-bds-gps-uart","provider":"Ebyte Official Store - IoT Module Manufacturer","version":"1.0","type":"link"}
