5.5 UART connector
The MPS2 and MPS2+ FPGA Prototyping Boards provide one general‑purpose female UART connector
that supports access to the FPGA.
The general‑purpose UART connector connects through a level-shifter to the FPGA. The meaning of the
UART signals depends on the design which you implement in the FPGA.
The following figure shows the general‑purpose UART connector.
