Key Features: -165 dBm sensitivity, 10 Hz updates, 99 search channels Designed for wearable use with the Flora system Only 30mA current draw RTC battery-compatible - sew a battery on to create an atomic-precision real time clock Internal patch antenna + u.FL connector for external active antenna This module is the best way to add a GPS to your wearable project. It's part of the Adafruit Flora series of wearable electronics, designed specifically for use with the Flora motherboard. Installed on the PCB is the latest of our Ultimate GPS modules, a small, super-thin, low-power GPS module with built-in data-logging capability!The breakout is built around the MTK3333 chipset, a no-nonsense, high-quality GPS module that can track up to 22 satellites on 66 channels, has an excellent high-sensitivity receiver (-165 dB tracking!), and a built-in antenna. It can do up to 10 location updates a second for high speed, high sensitivity logging, or tracking. Power usage is incredibly low, only 30 mA during navigation.The module is kept small and simple, we have a ferrite bead, filter capacitor and red fix LED on board. The LED blinks at about 1Hz while it's searching for satellites and blinks once every 15 seconds when a fix is found to conserve power. If you want to have an LED on all the time, we also provide the FIX signal out on a pin so you can put an external LED on.Item SpecificsSatellites: 33 tracking, 99 searchingPatch Antenna Size: 15mm x 15mm x 4mmUpdate rate: 1 to 10 HzPosition Accuracy: < 3 meters (all GPS technology has about 3m accuracy)Velocity Accuracy: 0.1 meters/sWarm/cold start: 34 secondsAcquisition sensitivity: -145 dBmTracking sensitivity: -165 dBmMaximum Velocity: 515m/sVin range: 3.0-4.3 VDCMTK3333 Operating current: 25mA tracking, 20 mA current draw during navigationOutput: NMEA 0183, 9600 baud defaultDGPS/WAAS/EGNOS supportedAGPS support (Offline mode : EPO valid up to 14 days )Up to 210 PRN channelsJammer detection and reductionMulti-path detection and compensationWeight: 5.43gDimensions: 30.5mm diameter x 5.98mm thick / 1.2" diameter x 0.24" thick Show more
