TAU1113 GNSS Module
TAU1113 is a cost-effective low-power GNSS positioning module based on the CYNOSURE III Lite GNSS SoC. It supports GPS/QZSS, BDS, Galileo, GLONASS and SBAS, and integrates SAW, LNA, flash memory and an antenna supervisor in a compact LCC package. With fast start-up, very low backup current and pin compatibility with mainstream GNSS modules, it is an excellent choice for tracking, telematics and battery-powered devices.
