u-blox 6 GPS Modules
Hardware Integration Manual
Abstract
This document describes the features and specifications of the cost
effective and high-performance LEA-6, NEO-6 and MAX-6 GPS
modules featuring the u-blox 6 positioning engine.
These compact, easy to integrate stand-alone GPS receiver modules
combine exceptional GPS performance with highly flexible power,
design, and connectivity options. Their compact form factors and
SMT pads allow fully automated assembly with standard pick &
place and reflow soldering equipment for cost-efficient, high-
volume production enabling short time-to-market.
