Hello,

sorry to bother about this trivial thing, but I just couldn't realize this on my own.

Namely, there is a resistor in the schematic - and it is marked as "0R00"... What does this mean?

The only explanation I could get my mind on was that it is a short circuit... but that one does not make sense, as the resistor is definitely there - why would it be 0 then?

Thanks in advance.

Best regards.

 

0R00 means 0.00Ω. They are sometimes used as jumpers.

 

It's a link or jumper.

 

A zero ohm resistor is commonly used as a jumper.

I use them all the time to link "optional" parts of a circuit together. In this way, I can have one PCB fab that performs multiple functions depending on how it is populated.

 

automatic part placement machines use 0 ohm resistors as jumpers. it makes it easier for them to handle. just a piece of wire with a resistor body on it.

 

Thank you all very much.

Best regards.
