Flora Wearable Ultimate GPS Module

Introducing the MTK3339-based GPS Module, the perfect solution for adding GPS functionality to your wearable projects. Designed as part of the Adafruit Flora series, this module is compact and powerful, ideal for integration into small, lightweight electronics. With -165 dBm sensitivity and the ability to track up to 22 satellites, it provides accurate positioning even in challenging environments. The module offers a 10 Hz update rate for fast, real-time tracking, making it perfect for high-speed applications. Plus, its low power consumption of only 20mA during navigation makes it an energy-efficient choice for wearable tech.

One of the standout features of this module is its built-in data logging capability. Using the internal FLASH memory, the GPS module can record time, date, latitude, longitude, and height every 15 seconds, storing up to 16 hours of data. Once the logging command is sent, the Flora mainboard can go into sleep mode to conserve power, while the GPS continues logging autonomously. This feature is perfect for applications where continuous tracking is required, and it eliminates the need for constant communication with the mainboard.

Additionally, the module supports an external active GPS antenna via a u.FL connector, providing flexibility for enhanced reception in areas where the internal patch antenna might struggle. It also features a fix status LED, making it easy to monitor satellite connections. Whether you're building a wearable navigation system or experimenting with location-based projects, this GPS module delivers high precision and reliability, making it a must-have for any tech enthusiast.
