The L86-M33 GPS GNSS Breakout Board is a game-changing device for anyone in need of accurate location data. This high-performance GPS module features advanced positioning technology that provides unparalleled accuracy and reliability, making it an ideal choice for a wide range of applications. With its compact and easy-to-use design, the L86-M33 GPS GNSS Breakout Board is perfect for use in drones, robotics, navigation systems, and much more. The board's powerful GNSS receiver provides precise location data even in challenging environments, ensuring that you always have access to the information you need. Whether you're a professional engineer or an avid hobbyist, the L86-M33 GPS GNSS Breakout Board is the ultimate solution for all your location tracking needs.

This breakout board integrates Quectel’s L86 an ultra-compact GNSS module that integrates a 18.4x18.4x4.0mm patch antenna along with an external antenna connector. It uses MediaTek’s new generation GNSS MT3333 chip. The board operates on 3.3V power supply and communicates with the target MCU through UART interface TX, RX, FON, and RESET pins. A V_BACK connection pin for a backup power supply is also available.

Through advanced AGPS (EASY) orbit prediction technology and power saving mode (AlwaysLocate technology), the L86 module achieves high performance and fully meets industry standards. EASY technology enables L86 to automatically calculate and predict orbit information for up to three days, and store this information in the internal RAM memory, which can achieve low-power fast positioning even under weak indoor signals. The use of AlwaysLocate technology enables the L86 to automatically adjust the positioning time according to different environmental conditions and operating modes, which greatly reduces the power consumption of the module while ensuring positioning accuracy.

L86 supports the intelligent detection of antenna plug-in and short-circuit protection. It also supports automatic switching between the built-in patch antenna and the external active antenna, and the positioning is continued during the switching process.

It is especially suitable for automotive, personal tracking, industrial-grade PDA and GPS receivers and OBD applications.
