How much to trim

So I got the ardiuno headers as mouser was out of the ones from the BoM. They are a bit long but I am wrroied about snipping too much off. Anyone know how much I should leave off the top?

They require something like 1/8 inch at least off. I think that’s like 3 mm. Maybe a little more. They allow for quite a bit of tolerance. You’d have to really mess it up. Start by taking a little off at a time until you can fit the connector all the way in, like you are clipping finger nails.

If you have a spare one, pull out the pins and use the plastic piece as a spacer and snip off the excess, the resulting part will be exactly the right height (after it’s been soldered in)

Thanks guys. Just being over cautious I guess. :slight_smile:
