[ARTY-Z7 / No Schematic (neither Rev. B.2 nor D.0 revisions provided by DIGILENT) matches the Hardware !]

I see : the blank sheet 6/13, corresponding to the USB-JTAG programming part, is not documented, which is on purpose from Digilent.

As a conclusion, the PCB REV.B I am using has to be associated to the schematic REV B.2.

I would recommend that, instead of having a 100% blank sheet, we would have a basic indication, something like "This page initially contained the USB-JTAG schematic, but for internal policy reason, it is not available for customers. Please contact DIGILENT for specific request.".

It would spare a lot of time.

Many thanks.

Dear elodg,

The text below the barcode (there are actually 2 barcodes... therefore I assume you mean the barcode "DB5BE18", the other one is "00183E03FF4F") reads "REV B".

I understand from your answer that the board I have bought should not exist, as no schematics provided by DIGILENT matches to the components.

This is quite a weird situation.

For instance, I have IC15, IC16, IC17 (just check the picture ZOOM.PNG) and no schematic, neither B.2 nor D.0, contains these chips...

What should I do now : throw away the board REV. B and buy a new one, hopefully it will correspond to an existing schematic ?

Would it be impossible to find @DIGILENT the schematic corresponding to the board I have bought ?

Is it a usual case in DIGILENT company that a board (available for sale) does not have a corresponding schematic ?

Many thanks.

Hello,

I am using a ARTY-Z7 board (please see attached picture) bought online from RS in July 2022.

Both schematics (rev. B.2 and D.0) available here on DIGILENT web pages do not correspond to the board I have :

https://digilent.com/reference/programmable-logic/arty-z7/start?redirect=1

It seems (not sure) that I have the Rev. B.

Here are the ICs I have on my board :

COMPONENT side : IC1, 3, 6, 20, 22, 23, 24

SOLDER side : IC2, 4, 5, 7, 8, 9, 10, 12, 13, 14, 15, 16, 17, 18, 19, 21, 25, 26

Nota : IC11 not found on the board and IC18  is not mounted

REQUEST :

would you please tell me WHERE I can download the schematic corresponding to my board ?

usually, is there any LAYOUT diagram for DIGILENT's boards ? Such diagram is quite useful. Is there any for the ARTY-Z7 board I have ?

Many thanks for your help.

 

[MCC118 / analog front-end schematic]

[2022.08.04 - 16:34]

Hello,

When the analog inputs of the MCC118 are not connected, we measure 1.75V. The electrical specifications read that the input front-end is a 1MOhm connected to the GND. Then, why do we measure 1.75V ? Is the front-end schematic available ? Where ?

Many thanks for your help.
