Hello guys!
Could anyone tell me what components this resistor (attached in the photo) is associated with? And what is its value and function?
I committed an accident when attaching the plate and ended up removing the component!

Grab your multimiter and check the removed Cap's capacitance.Also try measuring in diode more the continuity to vcc and gnd of capacitors board pads.
I suspect it may just be a decoupling cap.
If it's for decoupling you can use the previous one value or a slightly higher value.
Does the board work without it?
Also soldered components never should snap off.Usually you end up lifting the tracks.

Hi Andrei,
I haven't fed it yet, because I'm afraid of a possible "short circuit". I found the (original) component removed. Did you say it wouldn't be prudent to weld it back on the board?
If you accidentally desoldered it, you can just solder it back on, or solder another matching component on in it's place.
If it was pulled/snapped off, you may well have lifted one or both of the pads, in which case you cannot solder it back on, nor solder another part in it's place - there's no copper to solder it to anymore. You may be able to see the ripped off pad on the part if this happened, though it can be hard to recognize if you don't have experience with what this would look like. If that happened, you'd have to see if you could find some other place where something was connected to that same trace, and see if you could work out a way to get the part or replacement connected to it there, or maybe scratch the solder mask off the trace somewhere where you can do that; be aware that since that is quite likely a decoupling capacitor, you need to keep the length of the connections short.
Thanks guys for the clarifications.
