4. System Components
4.1 Cinterion Radio Module
There is a Cinterion radio module on the carrier board. It is possible to assembly four different radio
modules over the same footprint:
• EHS6 3G Gemalto Cinterion module
• EHS8 3G + GPS Gemalto Cinterion module
• ELS61-E 2G/4G (Cat 1) Gemalto Cinterion module
• ELS81 2G/3G/4G (Cat 4) Gemalto Cinterion module
The signal Gpio5_07 is used to enable/disable the radio module power supply. This module is connected
to iMX6UL-IND/IOT using USB high speed interface.
4.2 EEPROM
A 2Kbit EEPROM (Atmel AT24MAC402-XHM-T) is on the MTX-GTW II carrier board. The EEPROM is
controlled via the processor's I2C bus 1. Writing protection (WP) of the EEPROM is not available. The
base addresses can be taken from the following table. The first one is for memory bank and the second
one is for MAC address read.
This memory provides the MAC address of the ethernet interface of MTX-GTW II.

4.3 GPIO Expander
The iMX6UL-IND/IOT has not enough GPIOs to manage all the needed IOs and control external signals.
So, a PCA9570 is included in the design to provide the four additional GPIOs required.
