When standard GPS modules struggle to maintain a fix in challenging environments, the ATGM336H Dual-Mode Navigation Module delivers superior reliability. This advanced receiver simultaneously tracks both the US GPS and the Chinese BDS (Beidou) satellite constellations. By utilizing two networks at once, it significantly reduces Time-To-First-Fix (TTFF), increases positioning accuracy, and maintains a stable connection even in urban canyons or dense foliage.

Often used as a direct, high-performance upgrade to older NEO-6M modules, the ATGM336H outputs standard NMEA data over a simple UART serial interface. It comes mounted on a breadboard-friendly breakout board with onboard voltage regulation, making it incredibly easy to connect to standard 3.3V or 5V microcontrollers like the Arduino, ESP32, or STM32.

Perfect For:

• Drones & Autonomous Vehicles: Provide flight controllers and custom rovers with rock-solid navigation and reliable return-to-home coordinates.

• Global Asset Tracking: Build highly accurate fleet management trackers, custom dashcams, or anti-theft devices for vehicles.

• DIY Navigation Projects: Easily parse standard NMEA sentences to build custom digital speedometers, geocaching tools, or high-altitude weather balloons.
