About the Module
CHAPTER 1
The network-enabled ConnectCore for i.MX51 is a highly integrated and future-proof
System-on-Module (SOM) solution based on the new Freescale® i.MX51X application
processor with a high-performance ARM®Cortex-A8®core, powerful multimedia options,
and a complete set of peripherals.
The module combines the fast integration, reliability and design flexibility of an off-the-
shelf SOM with complete out-of-the-box software development support for platforms such
as Microsoft®Windows®Embedded CE 6.0, Digi®Embedded Linux ®and Timesys®
LinuxLink®.
With industry-leading performance and key features like a dual-display interface and a
hardware encryption engine, the module is the ideal choice for a broad range of target
markets including medical, digital signage, security/access control, retail, industrial/
building automation, transportation and more.
Complete and cost-efficient Digi JumpStart KitsTM for Microsoft Windows Embedded CE 6.0
and Linux allow immediate and professional embedded product development with
dramatically reduced design risk and time-to-market.

Module Pinout
The module has two 180-pin connectors, J1 and J2. The next tables describe each pin, its
properties, and its use on the module and development board. The DC parameters for each
I/O type are defined in the “I/O DC Parameters” section of Appendix A - Specifications.
The “Use on module” column shows the connection of the signals on the module. The format
of this column is “component: pad_name,” where “component” is the chip where the signals
are connected, and “pad_name” is the name of the pad where the signals are connected as
they are defined in the component’s datasheet.
