Reply:
> I just created the work order for this design change. I confirm it will be V6-1.
> If you list the old versions having the same problem, I will create a non-conformity dedicated for each version/execution.
> We will then know in case of new request for the old versions that we have to make design change before production.V6.12022-08-31Erik van der BijErik van der Bijhttps://ohwr.org/project/fmc-adc-100m14b4cha-hw/issues/7V5 - Wrong comment on Vadj in schematics2019-10-08T15:08:15ZProjectsV5 - Wrong comment on Vadj in schematicsOn the power supplies schematics page, a comment says "VADJ must be set
to 2.5V.".
But the fmc-adc mezzanine will work with other Vadj voltages (e.g 3.3V).
\=\> Define the allowed Vadj range for fmc-adc.
