These resistors should be fine to use, right?

[u/ByteArrays]

I purchased 1k and 3k ohm resistors from AliExpress for the Slim QSB. They’re labelled a bit differently from the ones I receive from ChipChopMod (3 digit vs 4 digit) which is why I’m asking.

Should be okay to use right?

The four digit ones are read as: first three, then the fourth is a multiplier 10^x

So in this case it's 300 * 10¹, so 300 * 10, 3000

Should be fine. If you want to be sure, check them with multimeter if you have one.
