## Overview

The Doudou GT-U7 GPS Module is a compact, high-sensitivity tracking device designed for professional-grade positioning in challenging environments. Compatible with popular platforms like NEO-6M and STM32, it features low power consumption, fast satellite acquisition via an active ceramic antenna, and real-time LED signal indication. Ideal for vehicle navigation, drones, and mobile devices, it ensures reliable location data even under dense urban skies or jungle canopies.

## Description

Module parameters:1. Size 27.6x26.6mm (1.09x1.05in), with positioning holes;2. Equipped with 2.54mm pitch in-line connection interface or select patch;3. Working voltage: 3.6V-5V (or use Micro USB to directly supply power);4. Working baud rate: 9600 (can be modified by yourself);5. With IPEX antenna interface, distribution of active ceramic antenna, can quickly locate;6. The module comes with LED signal indication and data backup battery;7. The onboard E2PROM can save parameter data;8. The NEMA output format is compatible with NEO-6M.Features:With high sensitivity, low power consumption, miniaturization, and extremely high tracking sensitivity, it greatly expands its positioning coverage. In places where ordinary GPS receiver modules cannot locate, such as under the narrow urban sky and dense jungle environment, GT-U7 can accurately locate. The module's high sensitivity, small static drift, low power consumption, light weight and small sizeApplies to:Car navigation, drones, vehicle monitoring, shared bicycles, mobile phones, cameras and other positioning equipmentPackage contains:GT-U7 GPS module x1IPX antenna x15pin 2.54mm pin x1

Review: Works Great with My Helcat V3 - Wired up to a Helcat V3 device and it "saw" 7 satellites on my windowsill (see attached photo). Be careful with wiring and setting the GPIO pins in the "settings/position" page in iOS (same in Android). I wired VCC to 3v3, RX to Pin 46, TX to Pin 45 and GND to GND. Software/App-wise, I used pin 45 for "GPS Receive GPIO" and pin 46 for "GPS Transmit GPIO" setting. I left the "GPS EN GPO" pin setting to "Unset" and it all worked fabulously! I purchased a case to hold the Helcat and the GPS and a new battery (smaller) but have not assembled as yet. I bought the Helcat V3 on desertcart with the case, battery, antenna and Helcat V3. The GPS will NOT FIT this case, as an FYI. You must use a case designed to fit everything including the GPS.
Review: Nice and inexpensive - Works great on either serial or USB; can be used "hybrid" with the PPS signal and USB for the data delivery which is nice on the Pi series machines which only have one serial port and you might ant that one for a console. One of these plus a "Pi" makes for a very nice and low-cost Stratum 1 NTP time server.

### ⭐⭐⭐⭐⭐ Works for a meshtastic base unit.
*by E***D on December 23, 2024*

I have this wired to a Heltec v3. Just need a switch to prevent it from being powered if the unit is off.
