LCD

The SoM-200 specification has provision for up to 24-bit LCDs (8-bits per RGB color). These lines can also
be used to provide analog VGA connectivity for use with a conventional monitor by adding a video DAC to
the Carr

ier. A Brightness PWM is also provided to allow for software control of the LCD’s Brightness.
