Simply connect a Micro USB cable and start receiving location data at 9600 baud — no microcontroller required.\n\nBuilt around the MTK3333 chipset with PA1616D module, it tracks up to 33 satellites on 99 channels with -165 dBm sensitivity and delivers up to 10 Hz position updates. On-board indicator LEDs show fix status, power, and UART activity at a glance.\n\nKey Features\n\n\nPlug-and-Play USB – Built-in CP2104 USB-to-Serial converter with Micro USB B connector\n\nGPS + GLONASS Support – Dual constellation tracking for improved coverage and faster fixes\n\n99-Channel Receiver – Tracks up to 33 satellites with -165 dBm sensitivity\n\n10 Hz Updates – Up to 10 position updates per second\n\nLow Power – Approximately 29 mA current draw during navigation\n\nPPS on Ring Indicator – Pulse-Per-Second signal output on the RI serial control pin\n\nDual Antenna Support – Internal ceramic patch antenna plus u.FL connector for external active antenna (auto-switching)\n\nBuilt-in Datalogging – Internal FLASH logging via LOCUS\n\nRTC Battery Backup – Footprint for CR1220 coin cell for warm starts and timekeeping\n\nStatus LEDs – Red fix LED, yellow RX/TX activity LEDs\n\nUSB Breakout Pads – 4-pin USB breakout for direct soldering to a USB host\n\nMounting Holes – Two holes for secure mounting\n\n\nIdeal For\n\nAdding GPS to computers, laptops, and Raspberry Pi\nGPS datalogging on embedded Linux systems\nLocation-aware desktop or Python applications\nNTP time synchronisation using PPS\n\n\nPackage Contents\n\n1× Adafruit Ultimate GPS with USB (fully assembled and tested)\n1× CR1220 coin cell holder (battery not included)\n\n\n\nNote: The updated PA1616D module is slightly taller (4 mm) than the original and has modified antenna query commands. Check the datasheet for details. CR1220 coin cell battery required separately for RTC backup.\n\n\nResources\n\n\nCircuitPython GPS Parsing Guide – Example code using pyserial for Python 3\nPA1616D Module Datasheet (PDF)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5170,"title":"Default Title","sku":"AF-4279","price":60.91,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
