Ribbon cables for Beagle. What is pitch?
« on: August 21, 2015, 09:58:38 AM »
As I start to assemble my new matrix, I am looking for ribbon cables from the beagle to the first P10. As I look on EBAY, I see 16 pin IDC cables and most of them feature a 'pitch'. I have NO idea as to what is meant by 'pitch'. If they all have the same cable and the same connector on the end.....What is pitch?? Here is an example. Every offering on ebay seems to have a different 'pitch'???

And another with a different 'Pitch"

Any online place where I can buy a lot of 10 2-3 feet long? recommendations?

The pitch is just the spacing of the conductors in the jack.
2.54mm is the "standard" pitch for the jack used on P10 (Hub75) cables.
Since it is a 2-row jack, the ribbon cable is sometimes listed as 1.27mm pitch.
The P10 name is the Pitch of the pixels (10mm apart)

I got all these from Amazon (and just made my own)

End connectors:

(and even though the picture shows 16 conductor, they sent me 24 conductor. I just peel off the last 8 conductors (leave the Red one alone!!! That is Pin 1).

crimper (this is not necessary, but convenient)

Any word on the strain relief for the end connectors as well?

Oh, nevermind, I looked at the photo better and see it does come with strain reliefs.  The ratings for the connectors seem to be rather poor.

Strain relief is not required (but I added it on mine)

Would you happen to know where I can purchase the power connectors and terminals as well?

CFOL (CrockettFantasyofLights) has the power cables on Pre-Sale now. They also will have the power distribution boards soon, and those are very useful when putting together larger arrays of P10s

Power cables should come with the panel when you purchase.
