EZ-GPS-G Product Specification

1 General Description
USB GPS Dongle, Plug and Play. Works with most GPS software programs that conform tothe NMEA-0183 Standard. Most mapping software packages will work with the EZ-GPS-G.
The output is set at 4800 baud, NMEA. The EZ-GPS-G is based on the Inventek ISM3333C6.1 GPS module.
For detailed specification, please refer to the Inventek Media Tek GPS module, partnumber ISM3333-C6.1. The GPS has a USB host interface and a female
SMA connector for a direct antenna attachment. We suggest the use
Inventek active waterproof dome antenna part number, ANTDOM-01WPM that connects directly to the EZ-GPS-G.
The EZ-GPS-G is based on the MediaTek MT3333 All-In-One multiGNSS SoC and includes an on-chip CMOS RF, digital baseband, ARM7
CPU and embedded flash. The ISM3333 can achieve the industry’s highest level ofsensitivity, accuracy, and Time-to-First-Fix (TTFF) with the lowest power consumption in asmall-footprint lead-free package.
The ISM3333 acquires and tracks satellites in the shortest time even at indoor signallevels. The ISM3333 supports various location and navigation applications, including
autonomous GPS, GLONASS, GALILEO, SBAS ranging.
The Inventek ISM3333 is ideal for a wide range of mobile and personal tracker, drone andindustrial applications. The ISM3333 features high sensitivity (-165dBm tracking
sensitivity), for enhanced performance in dense urban environments.

The EZ-GPS-G standard firmware is programmed to support GPS and Galileo
simultaneously. This module has the ability to supports any two: GPS + GLONASS +Galileo significantly improve on performance and GPS sensitivity.
The ISM333 is suitable for a wide range of target applications, including the most compact: Portable Devices
 Asset Tracking / Personal Safety
 Sport Cameras / Equipment Navigation devices
 Fleet management
 Asset tracking
The ISM3333’s world class performance suits it to navigating urban canyons, as well as
wide-open spaces.

5.4 EZ-GPS-G Host Interface
FTDI232 Virtual COM port (VCP) drivers cause the USB device to appear as anadditional COM port available to the PC. Application software can access the USB
device in the same way as it would access a standard COM port.

6 Product Compliance Considerations
RoHS: Restriction of Hazardous Substances (RoHS) directive has come into force since
1st July 2006 all electronic products sold in the EU must be free of hazardous materials,
such as lead. Inventek is fully committed to being one of the first to introduce lead-freeproducts while maintaining backwards compatibility and focusing on a continuously highlevel of product and manufacturing quality.

7 Packaging Information:
The module can be ordered with or without plastics.
