Fully populated. A fully populated module includes on-board Ethernet PHY,
Ethernet magnetics with RJ-45, a USB hub and Type A female connector.
With Ethernet but no USB Host. With this setup, Ethernet PHY or Ethernet
magnetics with RJ-45 are on the module. The module does not have an on-
board USB hub and Type A female connector, although USB Host and Device
signals are available on the edge connector.
No additional on-board connectors. With this setup, there is no Ethernet RJ-
45 with integrated magnetics on the module, but does have the Ethernet PHY.
The module does not hav an on-board USB Hub and type A female connector.
Note: Modules without an on-board Ethernet connector provide the Ethernet
PHY signals through the SO-DIMM edge connector.
Modules with on-board USB hub ahave access to hub ports 3 and 4
through the SO-DIMM edge conector.
Modules withouth on-board USB hub have access to HDM!, DP1,
GPIO16, and GPIO17 through the SO-DIMM connector.
All modules have access to the USB device only signals which require
an external PHY through the SO-DIMM connector (see appendix A,
USB Device only Table).
Design aid schematics are available for interfacing to all of the module
versions.
See the cc9c-wi-9c_baseboard_design_aids file on the Digi website
under Support> ConnectCore 9C or ConnectCore Wi-9C
documentation.
See Appendix A, the Module / SO-DIMM signal characteristics Table.
Additional population options are available. For information, contact your local Digi
sales office or distributor.

Module layout
The module design you use depends on whether you want to use the ConnectCore
Wi-9C wireless capabilities. The basic footprint for the ConnectCore 9C and
ConnectCore Wi-9C is the same; an extension of the footprint provides the active
components and antenna connectors for wireless functionality.
Note: The ConnectCore Wi-9C module is populated with either one RP-SMA
connector, two RP-SMA connectors, or 2 U.FL connectors (see
“ConnectCoreWi-9C configurations” on page 8 for all module configuration
options). The U.FL connectors are located in the same positions as the RP-SMA
connectors, but do not extend past the edge of the module.

Ethernet
connector pins There are eight Ethernet connector pins in the upper portion of the connector. Pin 1
is in the upper left corner of the connector, above the yellow LED. Pins 4, 5, 7, and
8 are used with Power-over-Ethernet (PoE) only (see “802.3af Power over Ethernet
(PoE) pass-through connector, P5” on page 13).
Ethernet LEDs The RJ-45 connector has two LEDs located near the outer lower corners of the
Ethernet port. These LEDs are controlled by the Ethernet PHY on the module, and
are not programmable.
