Microzed - module and connectors footprint

It would be great for the community to have a footprint of the 2 connectors of the microzed as eagle device to make sure that they are in the right position for designing individual Carrier Cards.

Maybe Avnet could provide such a footprint???

Thank you.

We are looking at providing

We are looking at providing an easy-to-use footprint for MicroZed that you could use to design your own Carrier board. We use Altium, so that would be the native format. Altium also has the ability to export to PADs. It does not seem to have Eagle export capability. Do you know if Eagle can import Altium or PADs?
 
Thanks for a great suggestion!

Altium footprint

I am also using Altium and would like if you could share the library component you have used for the carrier board. I have made my own one, but it would be better to have one I am 100% sure it will fit with my carrier board I would like to design.

If it's not too much trouble,

If it's not too much trouble, maybe one possibility is Eagle’s “User Language Programs (ULPs)”.

I found the following ULP here “http://www.cadsoftusa.com/downloads/file/import-accel.ulp”:
import-accel.ulp
“After initial export of P-CAD / Altium and Protel boards and schematics to ACCEL ASCII format (also kown as TangoPRO ASCII or P-CAD ASCII ) you can import your designs herewith into EAGLE. Beside English and German this ULP also supports Russian language.”

Mounting holes dimensions

I'm designing a carrier board for the MicroZED, but I can't find in any documentation the diameter of the mounting holes on the 4 corners of the board. I'd like to match them on the carrier, and also use the same hardware for other mounting holes on the board. So in there a number for those holes? (Note that I can find the positions of the holes in the HW User Guide.)

P.S. I have geda PCB footprint for the microheaders that I'd be willing to share, but this forum doesn't seem to have a way to attach files.

This would be great, thanks a lot.
I think the best way to share it is to create a Community Projects here http://www.zedboard.org/projects.
Again, thanks for sharing your work.

The 4 corner holes are 125

The 4 corner holes are 125 mil diameter.
 
As suggested by Mangibu, you can share your work through the Community Projects page.

connector assignment

i'm a long time user of AVNET evals with a faint glimmer of hope this suggestion reaches the design engineer/layout person.

please make the JX1/2 pin assignments as symmetric as possible, this way i can make an accessory card and attach it to either (or even better, both) connector(s) with out having a carrier board. imagine one ADC card (about 3/4 the width of microzed) that will work on either connector.

please do continue to make the connector symmetric about the left/right axis, these can pass through the accessory card from top to bottom, where you can

i understand placing JTAG on one and PMOD on the other,
but changing the assignments after pin 90 just seems unnecessary.

or maybe a rev. can be made now if the board is in ECO...

reading further from my list,
thanks for making the connector symmetric about the left/right axis,
i can pass these signals through my accessory card from top to bottom,
where you can i can place another JX1/2 and start fresh, imagine four ADC cards stacked 2x2...

concerning the way JX1/2 are currently laid out,
i understand placing JTAG on one and PMOD on the other,
but changing the assignments after pin 90 seems sloppy.

p.s. thank you for using dual row connectors for JX1/2 and not that crappy VITA57.1 FMC which you can't probe, verify if it's soldered, fan out properly nor get vertical separation...down with VITA and it's mixed mode HPC/LPC thing! <soap box burned>

Altium Symbol/Footprint now available

Avnet has released an Altium symbol and footprint for the MicroZed. This is now posted under "Layout" on the MicroZed Docs page: http://www.zedboard.org/documentation/1519.
 
Make sure to read the README. You will have to manually add the two JX connectors to your BOM, along with the specific MicroZed version to your system assembly BOM.
 
Legally, I also have to say use at your own risk. Please verify our work in your own design. If you find an issue, please address it here through the forums.

Accessing and Using Altium Symbol / Footprint

Has anyone downloaded and used the provided Altium footprint? The vault file provided shows up as Avnet temporary vault (error unknown vault) on my system. It seems Altium wants the server address and login info to access the footprint and schematic symbol.

Thanks for catching the issue

Thanks for catching the issue.
 
We posted the incorrect .CmpLib file by mistake. We will replace it with the correct .IntLib type file.

RE: Thanks for catching the issue

An update for those who discover this thread and are looking for the footprints:

One engineer working on a new design discovered that the MicroZed footprint we provided, when used in a new MicroZed Carrier design, did not enable Altium to generate the appropriate information for a contract manufacturer to build from this footprint. Since certain information was missing from a pre-build footprint and this was causing frustration for customers, we have removed the footprints listed from the zedboard.org site.

However, full Altium PCB design source project files for the MicroZed carrier boards can be obtained from your local Avnet FAE and this can be an excellent starting point for you to base your own carrier design off of these already proven files.

Refer to this thread here:

Sorry, if this thread has caused any confusion on this topic. Hopefully this post will help to set the record straight!

Best Regards,
