I am in the process of designing a PCB for a solder kit that receives NeoPixel type LEDs, the ones with the short head:

Short head NeoPixel

Now, there seem to be different pinouts:

Maybe someone can shed some light on this: Is there any system so that I can know when ordering which pinout I will get?

Update

I did a little bit more digging, which may answer the question. There seem to be two large manufacturs of the NeoPixel type THT LEDs with short head:

  • Worldsemi Co. Limited, making the WS2812D-F5 mentioned above:

    (DIN, GND, +5V, DOUT|
    
  • Shenzhen LED Color Opto electronic Co.ltd, making the SK6812D5 (datasheet) and the APA106:

    (DIN, +5V, GND, DOUT|
    

My take is that it’s best to order from vendors that clearly state the model number. Interesting is also the WikiLEDia list of chips sorted by manufacturer.

  • \$\begingroup\$ As said, the system applies to components just as well as it applies to cars, houses, fruit, meat, shoes and drugs: Reputable sellers will provide you with goods with a specification that actually applies. Other sellers shouldn't be getting your money. Full stop. I have zero sympathies for people getting scammed on aliexpress, amazon marketplace, or banggood. \$\endgroup\$ – Marcus Müller Mar 23 at 13:05
