I got a 30 RGB Led strip with WS2812B:
\nhttp:\/\/www.tweaking4all.com\/wp-content\/uploads\/2014\/01\/WS2812.pdf<\/p>\n
Its digital, it operates on 5V.\u00a0 Each led draws approximately 50 mA at 5 V with red, green, and blue at full brightness
\n-> 1.5A<\/p>\n
5v 2A power supply will do it.<\/p>\n
There is an issue, the signal voltage should be same. So either I get a step-up module 3.3->5v, or I run everything at 3.3, which is not recommended, so it should be temporary solution.<\/p>\n
According to this:

I should use 1N4001 diods.. but I’ll be using 1N4148, they should be similar choice<\/p>\n
Connecting the data line to GPIO 18<\/p>\n
