Detailed Description
1. 8 Slide switches: One side of each of the eight slide switches is tied to GND, while the other side is pulled
up to 2.5V. There is a 10K series resistor for each switch which enables these signals to be used at lower
voltages without damaging the FPGA. These switches are silkscreened SW0-SW7. SW0 is on the right
most side.

2. There are 8 LED's in a linear fashion, co-located with the slide switches. Each is tied to GND through a
300 Ohm resistor. LD0 is on the right most side. The LEDs illuminate with voltages as low as LVCMOS12.
