Unmentioned Resistors on Scaler ALT

[jestern]

Hi guys on the BOM there is no mention for

R4 R6 R18 R20
for the schematics + -5 V -> 1V
and
for the schematics 1V -> 5V

I assume they are left empty, am I correct?

Thanks

You’ve probably seen the threads & finished docs already but for everyone else, here’s a link to a very helpful post that clears all this up.

C5 Scaler BOMs Missing Resistors?

There has been ongoing confusion about the Scalers, and only recently someone put in a big effort to clarify the options for us… Check out the spreadsheet shared in this topic: Cadet Scaler BOM clarity - #18 by Z0NK0UT I’m hugely thankful for their work! And don’t be surprised if the version you intended to build is opposite to what you expected

thanks but that sends me to a page for the ±5 to 0-1 I am fixing the opposite.

check the tabs on the bottom of that DOCs page. it lists all possible builds

Hopefully @Martijn’s suggestion above does the trick.

Yes sorry I had not checked the tabs properly
