USB/TTL Raspberry Pi GPS tracker is a small GPS location module. It is using L80-39 GPS chip, which includes 66 search channels and 22 simultaneous tracking channels. These features can improve its satellites connection speed.

GPS tracker has USB and TTL two ports, it is easy to be used with Raspberry Pi, Arduino, STM32 and other kind of microcontrollers. And it is totally compatible with most of Raspberry Pi, like Raspberry Pi 3 Model B, Raspberry Pi 2 Model B, A+, B+, Zero .etc.

The GPS module uses NMEA0183 communication protocol, integrated ultra-small SMA antenna connector.

Features:

• -165 dBm sensitivity, 1Hz (Default), up to 5Hz, 66 channels
• At least 100mA current draw to startup.
• PPS output can be used to coordinate time with satellite.
• Internal patch antenna which works quite well when used outdoors SMA connector for external active antenna for when used indoors
• Fix status LED blinks to let you know when the GPS has determined the current coordinates
• EASY™, advanced AGPS technology without external memory
• Support time service application which can be achieved by PPS sync NMEA feature
• Built-in LNA for better sensitivity
• RTC battery-compatible
