I’ve done a load of projects using led strips with ws 2812 5V pixels and the raspberry pi neopixrl library as detailed in the fine tutorial by Adafruit
https://learn.adafruit.com/neopixels-on ... i?view=all
This used a level shifter to shift the pi 3.3v pwm signal up to 5V that the led strip is happy with. It also used a suitably high current 5V power supply for the leds
I’d like to use a 12v strip for another project for a variety of reasons and have found a suitable candidate on eBay

I’ve got a suitable 12v power supply but am a bit lost on the signal line. Do I use the same as the 5V strip or should I shift up to 12v using another level shifter??
Also, is there an advantage if using a higher voltage signal line esp chalky as the strip I went to use is about 8m long?
