Overlay images or text can be displayed on top of the compressed output streams, preview
streams, or composite video output. The overlaid video may be sourced from either the
composite video input or a decoded compressed stream. BMP and PNG image formats are
supported, with 24 or 32 bits per pixel and up to eight transparency levels.

Model 2253 supports three general purpose input/output signals (GPIOs): two inputs and
one output. One input and the output are opto-isolated.

The board implements a USB 2.0 high speed interface which also provides power for the
device.
