 +[[http://paperpcb.dernulleffekt.de/doku.php?id=other_boards:vga_signal_generator|VGA Signal Generator]]\\
 +HSYNC and VSYNC signals are squared pulses of +5V, and the RGB signals take values in a continuous analog voltage range from +0V (absolutely dark) to +0.7V (maximum brightness).\\
 +
 +=== Connection ===
 +H-Sync -- 68 Ohm -- Pin 03\\
 +V-Sync -- 68 Ohm -- Pin 10\\
 +R -- 470 Ohm -- Pin 04\\
 +G -- 470 Ohm -- Pin 05\\
 +B -- 470 Ohm -- Pin 06\\
