L218 Introduction
Summary
L218 is a low power and high performance four frequency GSM/GPRS (850/900/1800/1900) module, and integrates high-performance global positioning navigation Chip. The utility model has the advantages that the LCC package is easy to be welded, and the rapid production of the module can be realized through the standard SMT device Demanding applications.
L218 has a very small package, a wide range of operating temperature and internal integration of the TCP/IP protocol and fast positioning function. Especially suitable for size Sensitive tracking devices and other applications requiring location.
