{"title":"Adafruit Ultimate GPS FeatherWing","handle":"adafruit-ultimate-gps-featherwing","url":"/products/adafruit-ultimate-gps-featherwing","description":"The Adafruit Ultimate GPS FeatherWing brings precise, low-power GPS to the Feather ecosystem. 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 — all while drawing only 20 mA.\n\nSimply plug the FeatherWing into any compatible Feather board and you've got accurate location data plus time-keeping synced to GPS satellites. It includes a FET-driven ENABLE pin for low-power control, a CR1220 coin cell holder for RTC backup and warm starts, and a u.FL connector for optional external antenna use.\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\nDual Antenna Support – Internal ceramic patch antenna plus u.FL connector for external active GPS antenna (auto-switching)\n\nBuilt-in Datalogging – Internal FLASH logging via LOCUS for autonomous data capture\n\nPPS Output – Pulse-Per-Second signal on GPS fix\n\nRTC Battery Backup – CR1220 coin cell holder for warm starts and timekeeping\n\nFET-Driven ENABLE Pin – Turn the GPS module on/off from any microcontroller pin for low-power projects\n\nFix Status LED – Blinks at 1 Hz while searching, once every 15 seconds when fix is acquired\n\n\nIdeal For\n\nFeather-based GPS tracking and datalogging projects\nPortable location-aware devices\nGPS time synchronisation\nLow-power outdoor sensor nodes\n\n\nPackage Contents\n\n1× Adafruit Ultimate GPS FeatherWing (fully assembled with GPS module and coin cell holder)\n1× Header strip for soldering\n\n\n\nCompatibility Note: Works with all Feather boards except those with USB-Serial converters that use the UART pins. The ESP8266 Huzzah Feather and nRF52 Feather are not compatible.\n\n\n\nNote: CR1220 coin cell battery not included — required separately for RTC backup and warm starts.\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\nResources\n\n\nAdafruit Ultimate GPS FeatherWing Guide – Schematics, pinout diagrams, example code for Arduino & CircuitPython\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":11615,"title":"Default Title","sku":"AF-3133","price":50.16,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":101,"option1":"Default Title"}]}
