NeoPixel compatible RGB LED stick / strip : 8 RGB LEDs WS2812B 5050

The device runs exactly the same as the NeoPixel, including using the NeoPixel libraries. The only difference I can tell is that these have no Adafruit logo on the rear.

In my video, I'm running the strandtest example found on the Adafruit website here:

Notice when wiring it up, that there is a side with DIN for your signal line input. If you want to chain more together, then link the DOUT to the DIN of your next strip.

I highly recommend ensuring you follow the Best Practices guide from Adafruit to have the best results for this device. In particular, the usage of a capacitor across your 5v power terminals and a 300 to 500 Ohm resistor between the data output pin and the input pin to the LED strip. Here's the link to the Best Practices guide:

These LED strips expect a 5v signal line (to be attached to the VIN connector). Check what voltage your signal pins run at . Standard Arduino boards tend to run at 5v signal, but many modern devices such as the ESP32 seem to commonly run at 3.3v. A 3.3v signal line will not (in my experience) work at controlling the LED colours directly.

One way to use a 3.3v signal would be to run the signal through a Logic Level Shifter. A video guide on how to do this can be found here:

I've added some photos showing the dimensions, including the gap between the mounting/screw holes. Note that if you're looking to mount it or use standoffs, M3 is a little too tight, you'll need M2.5 ideally, or M2 if you don't mind it being a little loosey-goosey.

• Length: 50 mm
• Width: 10 mm
• Mounting Hole Gap: 25 mm
• Standoff screw size: M2.5 (2.5 mm diameter screw thread)
