AM572x EVM LCD Module Functional Block Descriptions
7.3 mSATA
There is a single mSATA connector on the backside of the LCD Module for use with SSD drives.
Only one SATA interface exists on the Processor Module. In order to use this interface on the LCD
Module, SATA_SEL jumper (located on the LCD Module) must be installed. This switches the SATA mux
on the Processor Module to the expansion connectors. When the SATA_SEL jumper (J1) is installed, the
eSATA on the Processor Module will no longer function. However, the connector can still function as a
USB 2.0 port.
7.4 miniPCIe
The miniPCIe (single lane) connector is identical to the mSATA connector. However, different pins are
used. miniPCIe can support several different functions such as WLAN/WIFI, Ethernet, Video, Analog,
GPS, and Memory.
7.5 COM8 Interface – Mobile Connectivity Expansion Connector
A single COM8 connector and interface is provided on the LCD Module. This connector is intended to
facilitate the plugging in of TI WiLink8 type devices for the addition of a Wi-Fi interface. The COM8
connector is a Samtec card edge type connector pn# MEC. This connector thus supports TI WiLink8 types
of boards, and more details about this connector can be found in the TI WiLink8 board documents.
The COM connector requires on 3.6V on the power supply. Thus a TPS74801 LDO regulator is used to
provide this voltage supply from the base 5.0V supply. The signals on the COM board are all 1.8 V voltage
level. Thus voltage translators are placed to convert to/from 3.3V of the AM572x rail for a particular signal
which is running at 3.3 V.
The TI WiLink8 evaluation modules have a built-in antennae. However, the LCD Module has holes cut to
accommodate a custom board with antennae if needed.

AM572x EVM Camera Module Functional Block Descriptions

The device video input port allows interfacing to a camera. The Camera Module board has either the
Leopard Imaging LI-3M02CM 3MP image with the Aptina MT911 sensor or the Omnivision 1MP OV10635
sensor module. Level shifters and buffers are provided on the board to interface to the 3.3 V of the
expansion headers. Control signals from the Processor Module controls the modules. These include I2C,
oscillator and power down. A dedicated clock oscillator is provided for the camera module.
