With 66 channels, -165 dBm tracking sensitivity, and up to 10 Hz position updates, it delivers accurate and responsive location data for a wide range of projects.\n\nVersion 3 introduces external antenna support via a u.FL connector and a Pulse-Per-Second (PPS) output. The module automatically detects when an active antenna is connected and switches over from the built-in ceramic patch antenna. A built-in datalogging feature lets you log GPS data to internal FLASH memory — even while your microcontroller sleeps.\n\nKey Features\n\n\n66-Channel Receiver – Tracks up to 22 satellites with -165 dBm sensitivity\n\n10 Hz Updates – Up to 10 position updates per second for high-speed tracking\n\nUltra-Low Power – Only 20 mA current draw during navigation\n\n5V Friendly – Built-in 3.3V regulator accepts 3.3–5V DC input with 5V-safe logic levels\n\nDual Antenna Support – Internal ceramic patch antenna plus u.FL connector for an external active GPS antenna (auto-switching)\n\nBuilt-in Datalogging – Logs time, date, longitude, latitude, and altitude every 15 seconds to internal FLASH (approx. 16 hours of storage)\n\nPPS Output – Pulse-Per-Second signal output on GPS fix\n\nRTC Battery Backup – Footprint for CR1220 coin cell holder enables warm starts\n\nENABLE Pin – Turn the module on/off via any microcontroller pin or switch\n\nFix Status LED – Blinks at 1 Hz while searching, once every 15 seconds when fix is acquired\n\nBreadboard Friendly – Standard 0.1\" header spacing with two mounting holes\n\n\nIdeal For\n\nGPS tracking and datalogging projects\nDrone and robotics navigation\nOutdoor and vehicle location systems\nTime-synchronisation applications using PPS output\nLow-power portable GPS devices\n\n\nPackage Contents\n\n1× Adafruit Ultimate GPS Breakout v3 (fully assembled and tested)\n1× 0.1\" header strip (for soldering)\n1× CR1220 coin cell holder (battery not included)\n\n\n\nTip: Most GPS antennas use SMA connectors — you may need a uFL-to-SMA adapter cable for external antenna use.\n\n\n\nNote: A CR1220 coin cell battery is required separately for the RTC backup feature.\n\n\nResources\n\n\nAdafruit Ultimate GPS Learning Guide – Wiring, datalogging, example code for CircuitPython & Arduino\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13049,"title":"Default Title","sku":"AF-746","price":60.81,"compare_at_price":97.0,"on_sale":true,"in_stock":true,"available_quantity":103,"option1":"Default Title"}]}
