The Ultimate GPS Module (PA1616D) is a high-sensitivity, 66-channel GNSS module built around the MTK3333 chipset. Weighing under 6 grams and measuring just 16 × 16 × 6.4 mm, it packs impressive performance into an incredibly small package — perfect for integrating GPS into custom projects and PCB designs.
With 10 Hz update rates, -165 dBm tracking sensitivity, built-in datalogging, and an internal patch antenna with optional external antenna support, this module delivers everything you need for high-performance GPS tracking at ultra-low power consumption.
Key Features
- -165 dBm Sensitivity – Excellent tracking even in challenging conditions
- 10 Hz Updates – High-speed location updates for real-time tracking
- 66 Channels, 99 Tracking – Tracks up to 33 satellites simultaneously
- Ultra-Low Power – Only ~20 mA while tracking, ~29 mA during navigation
- Built-In Datalogging – Log position data directly on the module
- Internal Patch Antenna – Plus uFL connector for optional 3V active external antenna (auto-detects and switches)
- PPS Output – Pulse-per-second output on fix for precise timing
- RTC Battery Compatible – Maintain time data between power cycles
- 3.3V Operation – Standard logic-level voltage
- Ultra Compact – Just 16 × 16 × 6.4 mm
Ideal For
- Custom PCB designs requiring GPS integration
- High-speed GPS logging and tracking applications
- Drone and UAV navigation systems
- Wearable and portable location devices
- High-altitude projects (reported working up to ~32 km altitude)
Package Contents
- 1× PA1616D GPS Module (raw module only — no breakout board included)
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- GNSS
- GNSS stands for Global Navigation Satellite System, an umbrella term for satellite positioning networks such as GPS, GLONASS, Galileo and BeiDou. Receivers use these satellites to determine position, and high-precision units can output a steady stream of serial position data.
- GPS
- The US satellite navigation system used by GNSS receivers to calculate position and time. Support for GPS is important because it is widely available and often used together with other constellations for more reliable positioning.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- RTC
- A Real-Time Clock keeps track of time even when the main processor is asleep or powered down, usually with a small backup battery. It matters for data logging and tracking projects that need accurate timestamps.
- UAV
- UAV stands for Unmanned Aerial Vehicle, an aircraft that flies without an onboard pilot, such as a drone or autonomous aircraft. Because airborne platforms have limited payload, factors like weight, power draw and any positioning features such as GNSS or RTK are often important considerations.
