Description: We know these look like a lot of our other LEDs, but they’re not! These are PTH Addressable RGB LEDs with a WS2812 control IC built right into the them. This PTH version is incredibly similar to its SMD cousin, except it is a lot simpler to solder into your project and is in a diffused 5mm package. This RGB LED has the control IC moved into the actual LED, so we wanted to offer this amazing product to you! They’re great when you need a lot of color from not a lot of board space, now more so than ever.
If you are looking for a great addressable LED in the more common LED form factor, then this is the perfect choice for you.
Note: Comes in packs of 5.

The bag is marked “SJ-F5-2811-F” There are two long leads and two short leads, as shown in the photo. However, the data sheet has a different photo and it is unclear which is pin 1 on the shipped parts.
Wired it up assuming flat side was pin 1 but didn’t work, don’t want to burn out any more without being sure!
I’ve long been looking for a frosted version that was also PTH. The color uniformity is spot on for the batch of 50 or so I bought. When you make your PCB footprint for these use an elongated pad with the smallest annular ring on the tight axis between pins. I got lots of solder bridges using circular only padstack.
When I purchased some WS2812B 5050 SMD LEDs, I found that I needed to solder in a capacitor across power for each LED. I bought a bunch of these PTH and assumed that I also needed one so I just went straight to it. But do these require a capacitor or is one built into the IC? On another note, I love how easy these are to daisy chain and control! So much easier than trying to control a lot of single LEDs.
While the datasheet makes mention that no external hardware is required, to be safe, I would suggest you use the smoothing capacitor on the power and in line resistor on the data line as shown in this tutorial https://learn.sparkfun.com/tutorials/ws2812-breakout-hookup-guide?_ga=1.248568967.1851504437.1417041706#hardware-hookup
Really easy to set up, following adafruit neopixle guide.
These worked as expected but it was hard since the datasheet doesn’t match what comes in the bag. Here is a picture of the actual pinout. https://a.pololu-files.com/picture/0J5433.1200.jpg?cdc0daa0c2fd98e38ed59b7d43758c6b
I wish the pin layout were more usable. A 2 by 2 pinout - on .1" pitch - I would give it 6 stars
