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 is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- GNSS
- GNSS stands for Global Navigation Satellite System, covering positioning systems such as GPS and similar satellite networks. It matters here because high-precision GNSS modules can output lots of serial position data that this product can send wirelessly to a computer or phone.
- 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 is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- 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
- Unmanned Aerial Vehicle, such as a drone or autonomous aircraft. The term matters here because high-accuracy GNSS and RTK are often used when a flying robot needs precise position information.
