{"title":"Adafruit Ultimate GPS Logger Shield - Includes GPS Module","handle":"adafruit-ultimate-gps-logger-shield-includes-gps-module","url":"/products/adafruit-ultimate-gps-logger-shield-includes-gps-module","description":"The Adafruit Ultimate GPS Logger Shield combines the popular Ultimate GPS module with a MicroSD card slot, giving your Arduino a complete GPS datalogging solution. Built around the MTK3339 chipset, it tracks up to 22 satellites on 66 channels with -165 dBm sensitivity and delivers up to 10 position updates per second.\n\nLog GPS data directly to a removable MicroSD card, or use the built-in FLASH datalogging for autonomous recording. The shield includes a prototyping area for adding your own sensors and LEDs, plus an RTC battery for accurate timekeeping even when powered off.\n\nKey Features\n\n\n66-Channel GPS Receiver – Tracks up to 22 satellites with -165 dBm sensitivity and 10 Hz updates\n\nMicroSD Card Slot – Log GPS data to a removable MicroSD card\n\nBuilt-in FLASH Datalogging – Autonomous internal logging via LOCUS\n\nLow Power – Only 20 mA current draw, half of most GPS modules\n\nDual Antenna Support – Internal patch antenna plus u.FL connector for external active antenna (auto-switching)\n\nRTC with Battery Backup – CR1220 coin cell included for up to 7 years of timekeeping\n\nPPS Output – Pulse-Per-Second signal on GPS fix\n\nStatus LEDs – Power, Pin #13, and Fix status indicators\n\nPrototyping Area – Large area for adding custom components\n\n\nIdeal For\n\nGPS datalogging and field recording projects\nGeocaching and location-triggered applications\nVehicle and asset tracking\nLocation-aware Arduino projects\n\n\nCompatibility\n\nArduino Uno, Duemilanove, Diecimila, and Leonardo\nNot compatible with Arduino Mega, ADK, or Due\n\n\nPackage Contents\n\n1× Adafruit Ultimate GPS Logger Shield (fully assembled and tested with GPS module)\n1× 0.1\" male header strip (requires soldering)\n1× CR1220 coin cell battery\n\n\n\nNote: MicroSD card not included. If you need to stack shields, use stacking headers instead of the included male headers.\n\n\n\nTip: For indoor or enclosed use, connect an external active GPS antenna via a uFL-to-SMA adapter cable — the module will automatically switch over.\n\n\nResources\n\n\nAdafruit Ultimate GPS Logger Shield Tutorial – Setup guide, wiring, and example code\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":7403,"title":"Default Title","sku":"AF-1272","price":58.43,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":71,"option1":"Default Title"}]}
