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.
