cbrnr: Only the "mV" issue remains. I didn't find anything in the comment you mentioned so I guess I'll have to dig a bit deeper.

cbrnr: Found it, it's because https://github.com/mne-tools/mne-python/blob/master/mne/io/brainvision/brainvision.py#L504. I guess I'll submit a new PR there and we'll wait for it to get merged.
cbrnr: Ready for review - all tests should pass once https://github.com/mne-tools/mne-python/issues/7537 is merged.
cbrnr: > cool, let's wait for the MNE merge. Should be soon. Can you please update What's New under the features section?

Done, but the test will fail until there is a new MNE release on PyPI with the change in https://github.com/mne-tools/mne-python/pull/7539 - do we want that?
sappelhoff: > Done, but the test will fail until there is a new MNE release on PyPI with the change in mne-tools/mne-python#7539 - do we want that?

Options:

1. we can adjust the tests to run `master` of MNE until the next release.
1. we can skip the failing test for now and until the next release of MNE (explicitly marking that test, because we know what's going on and why it's failing)
1. we can wait with this PR until MNE makes a backport of your fix

I prefer option 1. ... and then switching our CIs back to *not* running on MNE `master` once your fix is backported to `0.20`
cbrnr: I'm OK with 1 - can you make the change in a separate PR and then I rebase?

Set unit to microvolts
It seems like it is currently not possible to set the resolution and unit independently. As soon as `resolution <= -7` (which is `True` for the default), the unit is set to nV.

However, I just had a conversation with a BrainProducts developer regarding potential issues with the unit. Specifically, he said that BrainVision Analyzer currently expects the unit to be µV. If it's something else, auto-scaling doesn't work (at least the initial view).

Therefore, I would like to suggest to add an option that controls the unit. Possible values could include `'V'`, `'mV'`, `'uV'`, `'µV'`, and `'nV'`. I would set the default to `'uV'` (which is also the expected unit if the unit field in the exported file is empty).
