I/O Mapping Details
UART Interface
The UART is used to communicate with the PC. U3 does the level translation between the LVCMOS I/Os and the
RS232 port. The connector is a 9-pin D-type female. The interface details are included in Table 1.
Table 1. RS232 Interface
Expansion Header 1 Interface
Access to 40 I/Os are available to the user via the expansion headers J2 and J4. The connector type is a 2x20
0.100" center-to-center Berg stick, male. The interface details are included in Table 2.
