The on-board amplifier processes the video signal to produce a sequential stream of video
at the video output pin of the PI404MC-A8 module.
Illumination is by means of an integrated LED light source. All components are housed in
a small plastic housing which has a cover glass which acts as the focal point for the object
being scanned and protects the imaging array, micro lens assembly, and LED light source
from dust. I/O to the module is the 10-pin connector located on one end of the module.
See Figure 4, Mechanical Structure on the last page. The cross section of the PI404MC-
A8 is shown in Figure 1 and the block diagram in Figure 2.
