EVB-LIV3F / EVB-LIV3R Evaluation board
Introduction
EVB-LIV3x evaluation board is a complete standalone evaluation platform for
Teseo-LIV3x Tiny GNSS module.
Teseo-LIV3x module is an easy to use Global Navigation Satellite System (GNSS)
standalone module, embedding Teseo III single die standalone positioning receiver
IC working simultaneously on multiple constellations (GPS/Galileo/Glonass/
BeiDou/QZSS).
EVB-LIV3F is designed for top performance Teseo-LIV3F GNSS module.
EVB-LIV3R is designed for top performance Teseo-LIV3R GNSS ROM module.
