L86-M33 GPS GNSS Breakout Board

The revolutionary L86-M33 GPS GNSS Breakout Board stands as a groundbreaking solution for individuals seeking precise location data. This cutting-edge GPS module boasts advanced positioning technology, delivering unparalleled accuracy and dependability. Its versatile design, coupled with high performance, makes it an optimal selection for a diverse array of applications, including drones, robotics, navigation systems, and more. The compact and user-friendly L86-M33 GPS GNSS Breakout Board ensures ease of use while providing robust GNSS reception for accurate location data, even in challenging environments. Whether you're a seasoned professional engineer or an enthusiastic hobbyist, this breakout board serves as the ultimate answer to all your location tracking requirements.

This breakout board seamlessly incorporates Quectel's L86, an ultra-compact GNSS module featuring an 18.4x18.4x4.0mm patch antenna and an external antenna connector. Powered by MediaTek's cutting-edge GNSS MT3333 chip, the board functions on a 3.3V power supply and communicates with the target MCU through the UART interface (TX, RX, FON, RESET pins). Additionally, it offers a V_BACK connection pin for a backup power supply.

Employing advanced AGPS (EASY) orbit prediction technology and power-saving mode (AlwaysLocate technology), the L86 module achieves superior performance while adhering to industry standards. The EASY technology allows automatic calculation and prediction of orbit information for up to three days, stored in internal RAM memory, facilitating low-power fast positioning, even in weak indoor signals. The implementation of AlwaysLocate technology enables the L86 to autonomously adjust positioning time based on environmental conditions and operating modes, significantly reducing module power consumption while ensuring positioning accuracy.

The L86 boasts intelligent antenna plug-in detection and short-circuit protection. It supports seamless automatic switching between the built-in patch antenna and the external active antenna, ensuring continuous positioning during the transition process.

Tailored for automotive, personal tracking, industrial-grade PDA, GPS receivers, and OBD applications, the L86-M33 GPS GNSS Breakout Board stands out as a particularly apt choice.
