Zest_Radio_GNSS

Overview

The Zest_GNSS_L86 is an electronics development board for 6TRON open source platform. It is built around the L86-M33 GNSS module from Quectel.

GNSS stands for Global Navigation Satellite System and is a general term describing the American GPS and the Russian GLONASS global positioning system.

The L86_M33 module with an embedded patch antenna and LNA brings high performance of MTK positioning engine to the industrial applications such as GNSS and GLONASS.

The L86-M33 supports automatic antenna switching function: it achieves the switching between its internal patch antenna and an optional external active antenna through an U.FL header. Moreover, it keeps positioning during the switching process.
