Individual properties of Alvium USB cameras
Please consider individual properties of Alvium USB cameras to design applications
successfully. See
Performance and troubleshooting
on page 189 for details.
Bare board cameras
If you intend to design an application using bare board cameras, please consider:
•
Aligning the sensor to the lens is extremely difficult and expensive. Therefore,
we recommend you to do evaluation with housed cameras first.
•
Bare board cameras are specialized components. We cannot give all data
needed for any application in advance.
•
Please let us partner with you for bare board camera applications to ensure a
successful design.

For reference, keep the
sandwich label including the serial numbers
of the
Alvium chip and the camera itself with the camera. See
