{"title":"SparkFun GPS Breakout - Chip Antenna, SAM-M8Q (Qwiic)","handle":"sparkfun-gps-breakout-chip-antenna-sam-m8q-qwiic","url":"/products/sparkfun-gps-breakout-chip-antenna-sam-m8q-qwiic","description":"The SparkFun SAM-M8Q GPS Breakout features a u-blox SAM-M8Q 72-channel GNSS receiver with a built-in chip antenna. It supports GPS, GLONASS, Galileo, and BeiDou constellations simultaneously, providing improved positional accuracy and faster satellite lock times.\n\nThe board communicates over I2C via the Qwiic connector system, keeping your UART ports free for other peripherals. Standard 0.1\"-spaced header pins are also broken out for breadboard use. An onboard rechargeable battery powers the RTC, reducing time-to-first-fix from approximately 30 seconds (cold start) to around 1 second (hot start).\n\nKey Features\n\n\n72-Channel GNSS Receiver – Supports GPS, GLONASS, Galileo, and BeiDou for multi-constellation positioning\n\nBuilt-in Chip Antenna – No external antenna required for standard use\n\nQwiic I2C Interface – Plug-and-play connection with no soldering required\n\nOnboard Rechargeable Battery – Maintains RTC and orbit data for fast hot-start acquisition\n\nHighly Configurable – Adjustable baud rates, update rates, geofencing, spoofing detection, SBAS/D-GPS, and more via the SparkFun Arduino Library or u-center\n\nBreadboard-Friendly – 0.1\"-spaced header pins broken out alongside the Qwiic connector\n\n\nSpecifications\n\n\nGNSS Module: u-blox SAM-M8Q\n\nConstellations: GPS, GLONASS, Galileo, BeiDou\n\nChannels: 72\n\nInterface: I2C (Qwiic) and UART\n\nCold Start TTFF: ~30 seconds\n\nHot Start TTFF: ~1 second\n\nBackup Battery: Onboard rechargeable\n\n\nIdeal For\n\nGPS tracking and data logging projects\nGeofencing and location-aware applications\nDrone and robotics navigation\nArduino and Qwiic ecosystem projects\n\n\nPackage Contents\n\n1× SparkFun SAM-M8Q GPS Breakout Board\n\n\nResources\n\nSAM-M8Q Hookup Guide\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5346,"title":"Default Title","sku":"SF-GPS-15210","price":86.39,"on_sale":false,"in_stock":true,"available_quantity":245,"option1":"Default Title"}]}
