Mini Skinny RGB NeoPixel 4 wire connection?

by seefar on Fri Aug 09, 2019 6:59 pm

I've just ordered in some 60/m Mini Skinny NeoPixel strip and am not sure how I should connect to the wires that come soldered on to the strip (two wires go to a 2pin JST and the other two are bare).

It looks like the strip has the normal + / - / D pads which has the 4 wires and 2-pin JST throwing me off.

I haven't been able to find any detail on this (at least that I'm following) on the product page or forum. I wanted to double-check before accidentally frying the strip.

Thanks for any help,
Clayton

The free wires connect to the strip's 5V and GND rails.

The wires that go into the JST connector are for the data signal.. you need a data line and a GND line for that connection.

Thanks Mike.

When soldering new wires to the pads, at cuts, later can you simply use 3 wires (5v, ground, and one for data) โ€“ or do you need to do something special for the data pad with an extra ground wire?

When splicing strips, connect power ground and 5v from the last pixel of one strip to the first pixel of the next. If you have a lot of pixels (more than 100 or so) you should feed +5v and GND to both ends of the strip. If you have several hundred or more, you should feed power to several points along the strip.
