MAX-7 / NEO-7 / LEA-7
u-blox 7 GPS/GNSS modules
Hardware Integration Manual
Abstract
This document describes the features and specifications of the cost
effective and high-performance MAX-7, NEO-7 and LEA-
7
GPS/GLONASS/QZSS modules featuring the u-
blox 7 positioning
engine.
These compact, easy to integrate stand-
alone GPS/GNSS receiver
modules combine exceptional GPS/GNSS 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.
