Board to board connectors

Tags: #<Tag:0x00007fa35947ceb8>

Hello peeps,

I’m designing some PCBs to create letter signs that can be connected together horizontally.
I will use WS2812B for the leds and effectively each letter acts a little bit like a strip of those leds.
I need an input connector on the left side (ground, vcc, data in) and and output connector on the other side (ground, vcc, data out).

I’ve never done a board to board connection so I was wondering if you aware of any good connectors that are low profile.


90 degree male/female 2.45 mm pins , double lane, should do the job, unless you need polarization?

Is the double lane required for strength?

It’s not but it’s better for allightment, single lane tend to bend

Thank you, that’s exactly the type of information I needed from somebody with more experience.

I’d be interested in how you get on with the LED signs as it’s on my never ending list.

Would you be willing to document it?

I will, I’m no expert though :smiley:
