RS-232 UART (HPS)
The development board supports two UART interfaces that connect to a mini-USB
connector (J27) using a FT232RQ-REEL USB-to-UART bridge. The maximum
supported rate for this interface is 1 Mbps. Board reference D21–D24 are the UART
LEDs that illuminate to indicate TX and RX activity.
Table 2–23 lists the RS-232 UART pin assignments, signal names, and functions. The
signal names and types are relative to the Arria V SoC in terms of I/O setting and
direction.
