I think that’s the “wrong” chip, but it will still work, it will just take some more work to get it to work because when the software tries to upload, the chip signature won’t match (it looks for a 328P and a 328 won’t match). It’s just a matter of changing a small value to get it to upload, but it can be confusing. Don’t worry about that until it happens.

It looks like one of the pins on the crystal near the can chips are shorter to the case, which is ground. That shouldn't matter for the uploading but check that you don't have the same issue on the other crystal. No shorts, anywhere.

Also, make sure you're following the proper directions for burning a bootloader; you need to have ArduinoISP sketch uploaded to your Uno (you can't have anything connected to the uno while doing this), THEN you select the new programmer (Arduino as ISP), then connect to BlueSaab ISP header, then hit burn bootloader. You have to have the right 328 (if it's not a 328P, the chip signature won't match, but we're not there yet; it's a fixable problem).
