How much current can a nRF52840 pin sink before it is damaged

[John]

How much current can a nRF52840 GPIO sink before it's damaged? Will current limiting to 20mA be OK?

[John]

But this parameter isn't listed.

Ah - you're right!

That's a pretty fundamental omission!

Thanks for checking! How do I get this question answered? I hate these forums because I don't know if you are a Nordic employee or just an engineer like me reading these posts. Wish I could just submit a question and bypass this uncertainty.

Nordic people are pretty quick to answer. Much better than most other similar forums, to be fair.

You have the option to create a Private Ticket when you create the post.

I agree - it should really be made clear who are Nordic employees.

Most of the "real" Nordic people have a Nordic logo as their avatar - but not all, and there's nothing to stop any Tom, ***, or Harry doing that.

The Norwegian names also tend to be a clue!

If you look at a person's Profile, the Nordic people seem to have a 'Nordic Support Engineers' and/or 'Nordic Blog Authors' badge on the right:

But I still agree that it should be plain in the post - one shouldn't have to go searching for it.

Thanks!
