Overview
The STMicroelectronics Teseo-LIV3F is a standalone Global Navigation Satellite System (GNSS) module that embeds the TeseoIII single die standalone positioning receiver IC. This module operates simultaneously on multiple constellations, including GPS, Galileo, Glonass, BeiDou, and QZSS. It is designed to be easy to use, with embedded firmware and a complete evaluation environment that save development time. The Teseo-LIV3F is compact, cost-effective, and offers superior accuracy due to its on-board 26 MHz Temperature Compensated Crystal Oscillator (TCXO) and a dedicated 32 KHz Real Time Clock (RTC) oscillator.
