Interfaces
Module interface Surface mount device with solderable connection pads (SMT application
interface).
Land grid array (LGA) technology ensures high solder joint reliability and
provides the possibility to use an optional module mounting socket.
For more information on how to integrate SMT modules see also [5]. This
application note comprises chapters on module mounting and application
layout issues as well as on additional SMT application development
equipment.
Antenna Main GSM/UMTS antenna, UMTS diversity antenna, (active/passive)
GPS antenna
USB USB 2.0 High Speed (480Mbit/s) device interface, Full Speed (12Mbit/s)
compliant
Serial interface ASC0:
