Replacement power cables for RGB matrices?

by bibulb on Wed Sep 30, 2020 5:24 pm

I've been working with a few of the big ol' matrices, but after putting them into lots of different screw terminals over the years, the power cables have seen better days by this point. Is there a way to buy replacements of JUST those power cables?
Parallel to that, is there a definition of these specific molex connectors so that if I wanted to hack my own cables for specific lengths, I'd have the right size and pitch on those connectors?

I believe the power connectors are a 4-pin Molex type connector. We don't sell the other end which is a spade / fork type connector, but those would be easy to find at any hardware or automotive shop. Amazon has them too.

Found what appears to be the correct connector for the matrix end of things : vh3.96 4 pin. (Here's an Amazon link for the connectors, but you'll need to specifically select the 4 pin version : https://www.amazon.com/Davitu-Straight- ... 07QMV84CC/)
You'll not only need to crimp the fork connectors onto the far end, but you'll also need to crimp and set the connectors on the matrix side. That said, it'll still probably be much, much, MUCH faster than ordering prebuilt cables from Aliexpress or whichever.

(Sadly, the ATX 4 pin cable is the wrong pin pitch for the connector, which is a dang shame - that'd make building cables SO EASY otherwise!)
