Connector Rows

The conga-TR4 is connected to the carrier board via two 220-pin connectors (COM Express Type 6 pinout). These connectors are broken down
into four rows (rows A-B and C-D).
5.1

Primary Connector Rows A and B

The following subsystems can be found on the primary connector rows A and B.
5.1.1 Serial ATA™ (SATA)
The conga-TR4 offers two 6Gb/s SATA ports. A switch on the module routes them to the four ports of the COM Express connector. You can set
the two active ports via BIOS setup.
5.1.2

USB

The conga-TR4 offers signals for eight USB 2.0 ports. The signals for USB 2.0 ports 0-4 are routed from the SoC. The signals for USB 2.0 ports
5-7 are routed from a USB hub on the module.
The USB 2.0 signals can be combined with USB SuperSpeed signals to create up to two USB 3.1 Gen 2 ports and two USB 3.1 Gen 1 ports (1x
in R-Series). For more information, see section 7.4 "USB Host Controller".
5.1.3

High Definition Audio (HDA)

The conga-TR4 offers signals for HDA and supports up to three external codecs. This interface supports multiple codec configurations on a
single board as long as all codecs operate on the same voltage.
Note
COM Express modules only support up to three data inputs (HDA_SDIN[0:2]) as described in COM Express Specification 3.0. AC'97 audio
codecs are not supported.
