Package Included: 1* NEO-7M GPS Satellite Positioning Module Review: The more you know - Great price for the module and it works well and is recognized in U-blox U-center. What should be mentioned though, in order to use the sma connector (external antenna) you need to remove capacitor C2. Otherwise both antennas are connected creating an impedance mismatch (bad reception). Review: Internal antenna does NOT work! - This does not have an internal antenna. You MUST use the external antenna for it to work properly. Once I added a live external antenna it picked up and locked on 10 sats. But I did not get any views of Glonass on it. ## Features - 1.Get 51 Arduino STM32 microcontroller routine. - 2.With a USB interface, you can watch the computer positioning effect directly phone line. - 3.With the passive ceramic antenna and passive antenna amplifier, make better use of the individual effects. - 4.With SMA interface can be directly connected to an active antenna SMA. - 5.TTL level, compatible with 3.3V/5V systems.(Size:39*25.5mm) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07X5GVW6Q | | Additional Features | USB Phone Interface, Enhanced Antenna System | | Are Batteries Included | No | | Audio Output Mode | speaker | | Best Sellers Rank | #795 in Single Board Computers (Computers & Accessories) | | Brand | HiLetgo | | Built-In Media | 1* NEO-7M GPS Satellite Positioning Module | | Compatible Devices | Smartphone | | Compatible with Vehicle Type | Car, Truck, Motorcycle, SUV, RV, Boat | | Connectivity Technology | USB | | Control Method | Voice | | Customer Reviews | 3.8 out of 5 stars 97 Reviews | | Display Type | No Display | | Human-Interface Input | Microphone | | Included Components | 1* NEO-7M GPS Satellite Positioning Module | | Item Dimensions L x W x H | 1.54"L x 1"W x 1.54"H | | Item Weight | 0.02 Kilograms | | Manufacturer | HiLetgo | | Map Type | Satellite | | Map Types | Satellite | | Mfr Part Number | 3-01-1541 | | Model Number | 3-01-1541 | | Mounting Type | Panel Mount | | Special Feature | USB Phone Interface, Enhanced Antenna System | | Supported Satellite Navigation System | GPS | | Touch Screen Type | Resistive | | Vehicle Service Type | Car, Truck, Motorcycle, SUV, RV, Boat | ## Product Details - **Audio Output Mode:** speaker - **Brand:** HiLetgo - **Connectivity Technology:** USB - **Included Components:** 1* NEO-7M GPS Satellite Positioning Module - **Item Weight:** 0.02 Kilograms - **Map Type:** Satellite - **Mounting Type:** Panel Mount - **Product Dimensions:** 1.54"L x 1"W x 1.54"H - **Special Feature:** USB Phone Interface, Enhanced Antenna System - **Vehicle Service Type:** Car, Truck, Motorcycle, SUV, RV, Boat ## Images ![HiLetgo NEO-7M GPS Satellite Positioning Module for Arduino STM32 C51 Replace NEO-6M 3.3V/5V Power Supply - Image 1](https://m.media-amazon.com/images/I/51fbKK4vdTL.jpg) ![HiLetgo NEO-7M GPS Satellite Positioning Module for Arduino STM32 C51 Replace NEO-6M 3.3V/5V Power Supply - Image 2](https://m.media-amazon.com/images/I/516IwF5BCLL.jpg) ![HiLetgo NEO-7M GPS Satellite Positioning Module for Arduino STM32 C51 Replace NEO-6M 3.3V/5V Power Supply - Image 3](https://m.media-amazon.com/images/I/51Gcy8SKkqL.jpg) ![HiLetgo NEO-7M GPS Satellite Positioning Module for Arduino STM32 C51 Replace NEO-6M 3.3V/5V Power Supply - Image 4](https://m.media-amazon.com/images/I/51sSUxSQGML.jpg) ![HiLetgo NEO-7M GPS Satellite Positioning Module for Arduino STM32 C51 Replace NEO-6M 3.3V/5V Power Supply - Image 5](https://m.media-amazon.com/images/I/51+Du5sRIiL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ The more you know *by M***A on September 5, 2025* Great price for the module and it works well and is recognized in U-blox U-center.
