L86-M33 GPS GNSS Arduino Shield and Data Logger

The Arduino shield incorporates Quectel's L86, an ultra-compact GNSS module featuring an 18.4x18.4x4.0mm patch antenna and an external antenna connector. Utilizing MediaTek's latest GNSS MT3333 chip, the L86 module achieves exemplary performance, adhering to industry standards. Leveraging advanced AGPS (EASY) orbit prediction technology and power-saving mode (AlwaysLocate technology), the module excels in functionality. The EASY technology empowers the L86 to autonomously compute and forecast orbit details for up to three days, storing this data in internal RAM for efficient low-power rapid positioning, even in areas with weak indoor signals. Meanwhile, the implementation of AlwaysLocate technology allows the L86 to dynamically adapt positioning times based on varying environmental conditions and operational modes, significantly minimizing module power consumption without compromising accuracy.

The shield boasts intelligent antenna plug-in detection and short-circuit protection. Additionally, it supports seamless automatic switching between the internal patch antenna and an external active antenna, ensuring continuous positioning throughout the transition process.
