L218 Introduction
Overview
L218 is a Quad-band ( 850/900/1800/1900) module with low-power consumption, high performance . It combines GNSS technology with high-sensitivity receiver. Its LCC package make it easy to be soldered and produced quickly through standard SMT equipment, which adapts to the application that strictly requires cost effectiveness and efficiency.
L218 is capable of fast-positioning, build-in TCP/IP protocol, tiny package and wide work temperature. All of these make it suitable to dimension-sensitive devices and application scenarios of location.
