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.

Simply 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.

Key Features

• 66-Channel Receiver – Tracks up to 22 satellites with -165 dBm sensitivity
• 10 Hz Updates – Up to 10 position updates per second for high-speed tracking
• Ultra-Low Power – Only 20 mA current draw during navigation
• Dual Antenna Support – Internal ceramic patch antenna plus u.FL connector for external active GPS antenna (auto-switching)
• Built-in Datalogging – Internal FLASH logging via LOCUS for autonomous data capture
• PPS Output – Pulse-Per-Second signal on GPS fix
• RTC Battery Backup – CR1220 coin cell holder for warm starts and timekeeping
• FET-Driven ENABLE Pin – Turn the GPS module on/off from any microcontroller pin for low-power projects
• Fix Status LED – Blinks at 1 Hz while searching, once every 15 seconds when fix is acquired
