I think these two post's well answer that. ( https://hyperion-project.org/t…u-ws2813.2985/#post-11348 ). and ( https://hyperion-project.org/t…u-ws2813.2985/#post-11351 )

However the scheme in post #2 of this thread is the wiring for apa102's & Rpi & level shifter (SN74HCT125).

Yes i run a raspberry pi 3 and apa102 leds
I checked that posts hut i dont how that are related to this issue
Anyways i think for the wiring i need a design board in order to have clean connections
I found this products

The level shifter
https://thepihut.com/products/…hifter-3v-to-5v-74ahct125

Ic socket
Not sure if this one will work as it has 16pin instead of 14

Board for connection

I’m noob about this electronics components so not sure if these will be enough

Thank you for the support

Post #2 of this thread has a scheme.

Thank you
Whats the best way to connect level shifter and all the wires? It seems like a lot of connections to the ground

Well i figure its probably one of two things or maybe the combination of both:

1. Added the level shifter into the circuit.
2. Added another 5V line towards the middle of the led strip as well as also connected the 5V and ground at the end of the led strip. This way the current of 5V is consistant throughout the whole led strip which i believe is deffinately helping in that sense that the led strip is behaving/responding to commands better.

I have the same problem
Can you add a photo or scheme of the level shifter integrated into the wiring?

Just a question @Brindosch
Why the diagram of the tutorial is different to the connections of the pictures?
