Chapter 1: VC7203 Board Features and Operation
• Active cooling for the FPGA
The VC7203 board block diagram is shown in Figure 1-1.
Detailed Description
Figure 1-2 shows the VC7203 board described in this user guide. Each numbered feature
that is referenced in Figure 1-2 is described in the sections that follow.
Caution!
The VC7203 board can be damaged by electrostatic discharge (ESD). Follow standard
ESD prevention measures when handling the board.
Caution! Do not remove the rubber feet from the board. The feet provide clearance to prevent short
circuits on the back side of the board.
Note: Figure 1-2 is for reference only and might not reflect the current revision of the board.
