Hi,

I'm referring following document.

www.ti.com/.../scba009e.pdf

Must "Vision Placement Alignment Fiducial" shown on figure 7 be placed?

Or, is it unnecessary if it's no used?

Best Regards,

Kuramochi

The fiducial marker is printed on the silkscreen and does not affect the operation of the device. It is necessary only if you are actually going to use it.
