That schematic is to the A7-15T CMOD unit.. I'd like to see the power distribution network and power supply used on the 35T CMOD unit.

Hi @mzin92,

Welcome to the Digilent Forums!

The schematic linked above is for both the Cmod A7 15T and the Cmod A7 35T.  The regulator and rail information on page 7 of the Cmod A7 schematic is the same for either version of the Cmod A7 15 or Cmod A7 35T.

best regards,

Jon

Awesome thanks!

Just to verify, there is nothing different about any of the inductors/capacitors used on page 7 nor any of the capacitors used on page 4?

I'm building a board with the 35T unit and want to make sure I don't need to make any modifications.. Any thoughts or recommendations?

Is there a BOM anywhere?

Best Regards,

Mahdi

Hi @mzin92,

There is no difference in the schematic on page 4 or 7 between the Cmod A7 15T anf the Cmod A7 35T. 

We do not publicly provide the BOM.

What information are you looking for specifically?

best regards,

Jon

@kwilber Thanks for sharing!

 

@jpeyron

I'd like to get equivalent parts to the one's on the board including the inductors and capacitors. All of the other parts in the schematic have a little more detail in it

Inductors -> Resonating frequency, impedance, tolerances, etc

Caps -> Package size, voltage ratings, etc.

Thank you for all of your help!

Hi @mzin92,

I reached out to one of our design engineers about your thread and they responded :

"For discrete parts without part number in the attached excel spreadsheet see the following requirements:

All ceramic capacitors are temperature coefficient X5R, X7R or C0G, unless specified otherwise.
Capacitors without maximum voltage rating are 6.3V or greater.
Capacitors without tolerance specification are 10% (20% if 10% is unavailable) or better.
Resistors without power rating are 1/16W or greater.
Resistors without tolerance specification are 5% or better."

best regards,

Jon
