Power Supplies - Digilent Genesys 2 Reference Manual

• Connecting an HDMI/DVI, VGA, or DisplayPort monitor shows a demo image with a mouse pointer.
• Connecting a USB mouse controls the mouse pointer on the display.
• The OLED () shows the Digilent logo and various information on several pages. Advance between pages with the
BTNC button.
• The internal FPGA temperature, voltage and current readings of various power rails are shown on the OLED ().
• Connecting the board to an Ethernet network will acquire link, IP address and become "pingable" at the IPv4 address
displayed on the OLED ().
• Connecting the USB-UART port to a PC and opening a terminal (115200, 8, N, 1) shows status messages.
• Pushing BTNU records audio off the microphone input for five seconds and plays it back on the headphone output if
BTND is pushed, or line-out if BTNL. Similarly, BTNR starts a recording off the line-in jack.
• The LEDs are showing a scanning light bar.
• The fan starts when FPGA internal temperature reaches 60°C and stops when it drops back to 40°C.

2. Power Supplies

The Genesys 2 board can receive power from an external power supply through the center-positive barrel jack (J27). The
external supply voltage must be 12 V ±5 %. The Genesys 2 cannot be powered from the USB bus.
All Genesys 2 power supplies can be turned on and off together by a single logic-level power switch (SW8). Power supplies are
either enabled/disabled directly by the power switch or indirectly by other supplies upstream. A power-good LED () (LD15),
driven by the "power good" output of the on-board regulators, indicates that the supplies are turned on and operating
normally. An overview of the Genesys 2 power circuit is shown in Figure 1.
