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 [2]. This
application note comprises chapters on module mounting and application
layout issues as well as on additional SMT application development equip-
ment.
Antenna 50. 2 GSM/UMTS/LTE main antennas, 2 LTE Diversity/MIMO antennas,
(active/passive) GNSS antenna
USB USB 2.0 High Speed (480Mbit/s) device interface or
USB 3.0 Super Speed (5Gbit/s) device interface for debugging purposes
Serial interface Linux controlled:
ASC0:
• 4-wire (8-wire prepared) (plus GND line) interface unbalanced, asyn-
chronous
• Fixed baud rates from 115,200 to 921,600bps
• Supports RTS0/CTS0 hardware flow control
ASC1:
• 4-wire, unbalanced asynchronous interface
• Fixed baud rates: 115,200bps to 921,60bps
• Supports RTS1/CTS1 hardware flow control
ASC2:
• 2-wire, unbalanced asynchronous interface at GPIO9 (RXD2) and
GPIO10 (TXD2) lines used for debugging purposes (optional)
