14. FPGA_PROG_B Pushbutton Switch

The SP601 provides one dedicated, active low FPGA_PROG_B pushbutton switch, as
shown in

Power Management

AC Adapter and 5V Input Power Jack/Switch

The SP601 is powered from a 5V source that is connected through a 2.1mm x 5.5mm type
plug (center positive). SP601 power can be turned on or off through a board mounted slide
switch. When the switch is in the on position, a green LED (DS15) is illuminated.

Onboard Power Supplies

The diagram in
handling on each supply. The typical operating currents are significantly below the
maximum capable. The board is normally shipped with a 15W power supply, which
should be sufficient for most applications.
