Connector Subsystems Rows A, B, C, D
The COM 830 is connected to the carrier board via two
In this view the connectors are seen “through” the module.
Primary Connector Rows A and B
The following subsystems can be found on the primary connector rows A and B.
Serial ATA™ (SATA)
Two Serial ATA150 connections are provided via the Intel® 82801GHM
USB 2.0
The COM 830 offers 4 UHCI USB host controllers and one EHCI USB host controller provided by the Intel® 82801GHM
NOTE The USB controller is a PCI bus device. The BIOS allocates the necessary system resources when configuring the PCI devices.
AC'97 Digital Audio Interface/HDA
The COM 830 provides an interface that supports the connection of AC'97 digital audio codecs as well as HDA audio codecs.
Gigabit Ethernet
The COM 830 is equipped with a Marvell 88E8056 Gigabit Ethernet Controller. This controller is implemented through the use of the sixth x1 PCI Express lane. The Ethernet interface consists of 4 pairs of low voltage differential pair signals designated from GBE0_MD0 (+ and
LPC Bus
COM 830 offers the LPC (Low Pin Count) bus through the use of the Intel® 82801GHM
I²C Bus 400kHz
The I²C bus is implemented through the use of ATMEL ATmega168 microcontroller. It provides a Fast Mode (400kHz max.)
