GY-NEO-7M GPS Ceramic Antenna Module with optional External Antenna

The NEO-7M GPS module is a professional-grade GNSS receiver that combines small size, low power consumption, and robust satellite tracking. Powered by the proven u‑blox 7 engine, it supports GPS (and many variants also support GLONASS) and provides fast, accurate position, velocity, and time data. The module offers easy integration via a standard TTL serial (UART) interface and provides a PPS (pulse-per-second) output for precise time stamping. With its high-sensitivity receiver and optional external active antenna support, the NEO-7M maintains reliable performance even in challenging signal environments such as urban canyons or under partial foliage.

Key features

• u‑blox 7 GNSS engine for reliable positioning and low power use
• High-sensitivity receiver for weak-signal environments
• Typical horizontal accuracy in the metre-range (verify with SKU datasheet)
• Configurable update rate (commonly up to 5 Hz; configurable via UBX/NMEA)
• Standard TTL UART interface (easy to connect to microcontrollers such as Arduino, ESP32, Raspberry Pi via serial)
• PPS output for precise timing and synchronization
• Support for external active antenna (SMA / u.FL connector or pad depending on breakout)
• Small form factor — ideal for embedded and mobile applications
• Configurable via UBX binary protocol or standard NMEA sentences

Typical technical specification

• GNSS engine: u‑blox 7 series
• Frequency: L1 (1575.42 MHz), C/A code
• Channels: multi‑GNSS (GPS + optional GLONASS support on many variants)
• Position accuracy: ~2–3 m CEP (typical) — depends on constellation and antenna
• Time-to-first-fix (cold): typically < 30 s; hot/warm considerably faster
• Update rate: up to 5 Hz (configurable)
• Interfaces: TTL UART (primary), PPS output
• Supply voltage: typically 3.0–3.6 V (3.3 V typical) — include on-board regulator for 5 V support; check SKU
• Current consumption: low (tens of mA); varies by mode (check datasheet for sleep/active numbers)
• Antenna: requires active antenna for best performance; include built-in patch antenna

Applications

• Drone/UAV navigation and telemetry
• Vehicle and asset tracking systems
• Robotic platforms and autonomous vehicles
• Time synchronization (PPS) for data-logging and communications equipment
• Handheld and portable GNSS projects
