Leopard camera module

Hello!

I want to connect Leopard LI-3M02CM module to OMAP3530 based device. I follow XM-A3 and Leopard-DM365 schematics to figure out the internals and I don’t have the LI-3M02CM schematics itself.

Here what I found and ask for help:

At the Xm camera connector pin 24 is either 5V or 3.3V. However at Leopard-DM365 the pin 24 is CCD-DATA3 which can’t be 5V anyway. Can anybody clarify what voltage value and why should I connect to the pin 24? This Pin seems to be logic, not a power type. By the way at the module itself pins 24 and 26 are not connected.

Thanks in advance!

I haven’t really looked that close at the Leopard board, but I spent a lot of time going back and forth with the folks at Leopard Imaging on the proper pin out of this connector. And it does indeed work. You might try contacting the Leopard Imaging folks to see if they can offer an explanation. You can find the schematicsfor the Beagle supported boards here:

Dear Gerald,

Thank you very much! I have requested for schematics of the LI-3M02CM module yet. All other documents I have and they do not help. Of course I can just clone you part of XM but first I need to understand then to do.

There was a lot of confusion on this. The Leopardboard if I recall was pinned out for some “futrue” stuff that they were looking at doing. I never really understood exactly what it was.

Gerald,

Now I don’t understand what you mean :slight_smile:
