Expansion connectors

Pin 3: 3.3V
Pin 39
Pin 40
E connector
The two expansion connectors labeled E and F on the DXC95
board use 100 mil spaced DIP headers. Both connectors have
GND routed to pin 1, VU routed to pin 2, and 5V routed to
pin 3. Pins 4-40 for both connectors route directly to
individual CPLD pins. The connectors are separated by 400
mils, so any Digilent peripheral board can be used with the
DCX95 board.
The PC84 package used on the DXC95 board has 69 signal
pins available to the user (the remaining pins are used for
VCC, GND, and JTAG). Of these, 69, 3 are used for the
button, led, and clock, and the rest are routed to the E and F
peripheral connectors. Data rates of up to the full clock
frequency are attainable across the E and F connectors.
