Hello people,

I was trying to do something, and I have lost(it went flying from the tweezers) the resistor that was soldered into the place marked in pic.. So I want to make sure that I found the right resistor marking so i can place another one.. I think its RI10 (page 34 in pdf) but I'm not sure... I attached the schematics of the board too.

Thank you all!

If I read the silkscreen right, it would be RI2. The schematic shows that as a 0402 size resistor of 43 ohms, 5%.
That said, that silkscreen is hard to read and correlate exactly to the components vs that silkscreen.
I see RI10 as above the D13, which seems to be on the left side, top...
TP19 seems related to that vertical wire

Yes, you are right, I see it now! Thank you very much!
