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.
Log 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.
Key Features
- 66-Channel GPS Receiver – Tracks up to 22 satellites with -165 dBm sensitivity and 10 Hz updates
- MicroSD Card Slot – Log GPS data to a removable MicroSD card
- Built-in FLASH Datalogging – Autonomous internal logging via LOCUS
- Low Power – Only 20 mA current draw, half of most GPS modules
- Dual Antenna Support – Internal patch antenna plus u.FL connector for external active antenna (auto-switching)
- RTC with Battery Backup – CR1220 coin cell included for up to 7 years of timekeeping

Jargon buster
Plain-language definitions for the technical terms used above.
- GPS
- The US satellite navigation system used by GNSS receivers to calculate position and time. Support for GPS is important because it is widely available and often used together with other constellations for more reliable positioning.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- microSD card
- A microSD card is a small removable memory card used to store files such as audio tracks. For this product, the card is where the sound files live, so its capacity and formatting can affect how many sounds you can use.
- RTC
- A Real-Time Clock keeps track of time even when the main processor is asleep or powered down, usually with a small backup battery. It matters for data logging and tracking projects that need accurate timestamps.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- u.FL
- u.FL is a tiny snap-on antenna connector often used on compact wireless boards. A board with u.FL usually needs an external antenna, which matters if the product will be inside an enclosure or needs better antenna placement.
