GY-NEO-7M V2 Flight Controller GPS Module with EEPROM – Compatible with MWC & APM2.5 – Onboard Ceramic Antenna

Description

Description

The GY-NEO-7M V2 is a high-performance, multi-GNSS navigation module built around the advanced u-blox NEO-7M chipset. As a significant upgrade from the popular NEO-6M series, this module supports multiple global navigation satellite systems (GNSS), delivering faster satellite acquisition, improved positioning accuracy, and more reliable performance in challenging environments .

The NEO-7M chipset simultaneously tracks GPS, GLONASS, Galileo, QZSS, and SBAS (WAAS/EGNOS/MSAS) satellite constellations, providing a richer pool of visible satellites for enhanced positional accuracy and reliability . Whether you are flying a drone in an urban canyon, navigating a vehicle through dense tree cover, or operating an autonomous rover in a mountainous region, the GY-NEO-7M V2 maintains a robust satellite lock.

This module features a high-gain 25mm × 25mm active ceramic patch antenna that provides excellent signal reception sensitivity down to -161dBm tracking . An SMA connector is also provided for users who wish to connect an external active antenna for even greater signal quality in demanding installations .

Key onboard features include EEPROM memory that permanently stores all configuration parameters (baud rate, update rate, NMEA message settings) even after power loss, and a rechargeable backup battery that maintains the real-time clock and ephemeris data for hot starts with a time-to-first-fix as low as 1 second .

Operating from a wide 3V to 5V DC input with onboard voltage regulation, the GY-NEO-7M V2 is compatible with both 3.3V and 5V logic systems. It provides UART TTL serial communication at a configurable baud rate (default 9600bps), making it plug-and-play compatible with Arduino, ESP32, STM32, Raspberry Pi, and popular flight controllers including MWC (MultiWii) and APM 2.5/2.6 .

The bright LED signal indicator provides immediate visual feedback of GPS fix status — regular blinking confirms a successful 3D satellite lock. For advanced users, the module can be configured using u-blox u-center software via the onboard micro-USB port (where equipped), allowing detailed performance monitoring and parameter customization .

Whether you are building a drone with position-hold and return-to-home, a vehicle tracking system, or a marine navigation device, the GY-NEO-7M V2 offers the multi-GNSS performance, configuration persistence, and integration ease required for both hobbyist and professional applications .
