ESP-LyraP-CAM v1.1 why 1.5V and not 1.2?

Postby Jonathan2892 » Fri Sep 16, 2022 1:26 pm

Hey

I have two questions about the ESP-LyraP-CAM v1.1 Board.

1. Why is the LDO converting the 3.3V to 1.5V for DVDD since the datasheet of the ov2640 has a typical 1.2V for that?

2. The docs say, that this board can only handle ov2640 and ov3660. But what about ov5640? Without an auto focus module the ov5640 could also be used with this board or am I missing omething?

Best,
Jonathan

Becasue OV3660 is 1.5 V. Anyway, since there is always margin between datasheet and pratical use, I think these cameras should all work for short-term tests. If you want to design for products, it is better to design power circuit as datasheet says.
