# NeoPixel THT: Varying pinouts [closed]

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

Now, there seem to be different pinouts:

• Ordered on Amazon.de as WS2811 LED Chip:

(DIN, GND, +5V, DOUT|


This pinout I figured out myself. With several batches I got the same pinout. (The datasheet for these actually had different pinouts in different locations, and so I fried a few at first.)

• (DIN, GND, +5V, DOUT|


This pinout is in the datasheet WS2812D-F5-15MA-C1规格 书_18031509334119.pdf available on the Worldsemi’s web site.

• (DIN, +5V, GND, DOUT|


See the datasheet COM-12877.pdf on the SparkFun web site.

• Regular NeoPixels (long head), distributed by Adafruit as NeoPixel Diffused 8mm Through-Hole LED:

(DIN, +5V, GND, DOUT|


See the picture 1734-04.jpg on the Adafruit web site.

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.

• If you want consistency you have to buy from actual distributors, not random deal importers. This questionnis off-topic here. – Chris Stratton Mar 23 at 11:56
• 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. – Marcus Müller Mar 23 at 13:05
