Teseo-LIV3F (Flash-based) and Teseo-LIV3R
(ROM-based) are an easy-to-use standalone
Global Navigation Satellite System (GNSS) module
with an embedded Teseo III single-die positioning
receiver IC able to work simultaneously on
multiple constellations (GPS/Galileo/Glonass/
BeiDou/QZSS). The Teseo-LIV3R does not
support Galileo.
Teseo-LIV3F module supports data logging for
continuous storage of position, velocity and time
data inside its embedded 16-Mbit Flash memory.
A exible rmware solution for Teseo-LIV3F that
makes it easy to download new rmware and
software updates is available.

Block diagram and pin conguration
Within their 9.7 x 10.1 mm compact size, Teseo-LIV3F/R modules offer superior accuracy thanks to their on-board 26-MHz
temperature-compensated crystal oscillator (TCXO) and a reduced Time To First Fix (TTFF) relying to their dedicated 32-kHz
real-time clock (RTC).
