You likely need a level shifter

Hoo interesting, didn’t know about that. Which one should I use for this application?

@Phantom Hi the stripe itself got only 60IC so only 60 adrassable segments with 36 LED/Node eatch WHAT controller are you using with a simople WEMOS D1 ESP8266 you are well up to the thing without a levelshifter but use a RESISTOR for the Firt led to avoid backpower

I would advise using the SN74AHCT125N [image] Amazon.com: Bridgold 10pcs SN74AHCT125N SN74 Quadruple Bus Buffer Gates with... The SN74AHCT125N is a quadruple Bus Buffer Gate featuring independent line drivers with 3-state outputs. Each output is disabled when the associated output-enabl…

hummm, if I set 60 LED in the configurations the strip doesn’t light up all the way. It lights up completely only when I set it to 100. The controller I’m testing with is a ESP 8266 indeed. I have some ESP32 S3 I could also test with. I tried using a 150Ω resistor on the data line, but it actually…

@Phantom with the 8266 you dont need the Levelshifter as it outputs the 5V TRY configure 10LED see how many Nodes/Led are displayd on Segment 0 LED 0-10 Try to add a segment LED 5-6 give it a other color or even a Effect like fade or chase See howmany led got the effect if you dont like u…

[image] Magig_Wled: with the 8266 you dont need the Levelshifter as it outputs the 5V That’s not correct.

[image] kilrah: That’s not correct. Yep. Esp8266 is 3.5v output from the GPIO’s. Level Shifter highly suggested.

So I finally received the level shifter! My wiring looks like this: [image] At first it wasn’t helping much, but then I started probing and realized there is about 0.5v drop somewhere. Even though I supply 5v to the 5v rail I ended up with 4.5v at the IC. So I pumped up the voltage input voltag…
