1.6 USB
The USB port arrangement is as follows:
• USB 3.0 ports:
 Two ports are implemented with external front panel connectors (one blue and one
amber charging capable)
 Two ports are implemented with external back panel connectors (blue)
 Maximum current is 900 mA for each blue port, 1.5 A for the amber charging port
• USB 2.0 ports:
 Two ports via two single-port internal 1x4 1.25 mm pitch headers (white)
 One port is reserved for an M.2 2230 Module
 Maximum current is 500 mA for each port of the white headers (1 A total)
All the USB ports are high-speed, full-speed, and low-speed capable.
NOTE
Computer systems that have an unshielded cable attached to a USB port may not meet FCC
Class B requirements, even if no device is attached to the cable. Use a shielded cable that
meets the requirements for full-speed devices.

1.7 SATA Interface
The SoC provides one SATA port with a theoretical maximum transfer rate of 6.0 Gb/s. A
point-to-point interface is used for host to device connections.
The underlying SATA functionality is transparent to the operating system. The SATA
controller can operate in both legacy and native modes. In legacy mode, standard IDE I/O and
IRQ resources are assigned (IRQ 14 and 15). In Native mode, standard PCI Conventional bus
resource steering is used. Native mode is the preferred mode for configurations using
Windows* operating systems.
1.7.1 AHCI Mode
The board supports AHCI storage mode.
NOTE
In order to use AHCI mode, AHCI must be enabled in the BIOS. Microsoft* Windows* 10 includes
the necessary AHCI drivers without the need to install separate AHCI drivers during the
operating system installation process. However, it is always good practice to update the AHCI
drivers to the latest available by Intel.
