HPS fabric through the UART interface. The other one is to connect to the system
MAX10 device. It allows users to monitor various status of the board such as
temperature and voltage value from the Host.
The board uses a USB hub to allow two USB to UART interface (HPS fabric and
system MAX10) and a USB Blaster II circuit to share a Micro USB connector to
connect to the host. Users only need one Micro USB cable to establish several UART
and JTAG connections with the Host to transmit data.

USB to UART for HPS Fabric
The board provides a UART interface for users to communicate and transfer data with
HPS through the host. This interface is mainly implemented via a dual UART to USB
(CP2105). For detailed chip information, please refer to \Datasheets\UART_TO_USB\
of the system CD. It can convert commands and data from the host via USB protocol to
the UART interface and send it to HPS.
the HPS, CP2105 chip, and the Micro USB connector.
Table 2-24
lists the pin assignment of UART interface connected to the HPS.
