Can I purchase the 512-Mbit SDRAM memory extender separately from the TIDM-TM4C129X?

Hello Amanda,

The Memory extender is a not a saleable item. The Gerber file and BOM is given on the TI Design Website, which can be downloaded by the end user and sent to a PCB manufacturing/assembly house.

Does TI provide the Altium project files, not just the GERBERS?

Thank you.

Amanda

Hello Amanda,

No the Altium Project is not available as the board is designed specifically for the Connected Launch Pad and the Gerber files should be sufficient from manufacturing purpose.

Amit

They are sufficient, except that to use a standard PCB fabrication process we need the pads to be .025" not .024".

Hello Amanda

Is it a restriction from the PCB Manufacturing House?

Regards
Amit

Only a restriction to get their standard pricing. They can of course fabricate the board.

Hello Amanda,

When we originally did the design, we took 3 PCB houses and took the lowest cost rule from each one of them. Can you ask the PCB house if they can edit the gerber for the relaxed rules w/o affecting the connectivity.

Regards
Amit

Poster may also inquire of (other) Board Houses - determine just how (universal) such restriction appears...

Hello cb1,

I do see your's and Amanda's point. We have used ProtoExpress.

Amit

Hi Amit,

We use them as well - although (most) clients specify that we receive "3 bids" - and then decide via a "multi-point" matrix. (price alone rarely is the deciding factor...)

Hello cb1

In this case it was the rules for the best price point

Regards
Amit

It looks like the PCB house is willing to modify the gerbers (via pads to 0.025") and I manually verified that this should not cause any issues.

Hello Amanda,

Generally they do some gerber corrections to meet the requirements.

Amit

Perhaps Amanda's objective may be spread - yielding cost-saving for her firm - and advantages for others, here.

Unknown is Amanda's quantity - if a larger build was produced cost (usually) decreases - and "follow on" users could then - more quickly - receive such boards.

Some survey to gauge forum interest/desire may prove worthwhile - there may be opportunity for some here...   (and cost savings for all...)
