TD7740 VGA camera modules

Image sensor: OmniVision 1/5" OV7740 CMOS VGA sensor.

For more on organizing work around technical projects, read further details.

Module: solderless. Camera socket (SMK compatible) or flex connector (FPC). 8 x 8 mm module, mating on a standard camera module socket.

Active image size: VGA (640 x 480) at 30 fps, and smaller.

Output: digital RGB 8/10 bits, or YUV 8 bits.

A useful external technical reference is A3 / Association for Advancing Automation.

Lens: focal length 1.3 mm.

The variants

The family is ordered as TD7740 plus a four-character code, in which each position selects a physical option.

Variant	Filter	Mounting	Field of view
SBBB	Dual filter	SMK socket, 8 x 8 mm	100°
SBAB	Dual filter	SMK socket, 8 x 8 mm	90°
SBAC	IR filter	SMK socket, 8 x 8 mm	90°
SBAA	No filter	SMK socket, 8 x 8 mm	90°
SBDC	IR filter	SMK socket, 8 x 8 mm	128°
SBEC	IR filter	SMK socket, 8 x 8 mm	42°
FBAC	IR filter	Flex, 25 mm	90°
GBAC	IR filter	Flex	90°

All at 1.3 mm focal length, colour Bayer sensor.

Which variant to order follows from the installation geometry rather than from preference: the field of view is fixed by the distance and the coverage required, and the filter by the illumination.

Documentation

The archived documentation listed this material as NDA-restricted; this static build does not provide a request channel or the restricted files.

What an evaluation kit is for — and what an afternoon with one settles.

Deciding whether it fits

Start from what must be resolvable — the feature, its size, the working distance and the pixels the processing needs across it.

Then the lens calculation, which takes ten minutes and finds the real constraint before anything is ordered.

Then the filter, which follows from the illumination: infrared cut for visible colour work, dual band where an infrared illuminator is used at night, none for deliberate infrared imaging.

And the mounting, since one degree of tilt displaces the view by roughly 17 mm per metre — which makes mechanical tolerance an imaging specification.

What the documentation does not state

Anything absent from the data sheet is absent from this page too.

Nothing here is estimated or interpolated — which is the standing rule and the reason a thin page is thin.

Ask for what is missing. The information checklist shows what details matter, and where the answer is that a figure has never been characterised, that is itself informative.
