5V RGB LED LPD8806 Stripxels (32 per meter)
These are very similar to the WS2801 RGB Stripxel, but feature the LPD8806 controller IC instead.
Ok, so what's up with these RGB stripxels? What makes these individually controlled RGBs-in-a-strip different from the other Stripxels we have? Well, they're similar and different. They both:
- Run on 5V
- Use clock & data to shift-in RGB brightness values
- Have 32 SMD5050 RGB LEDs per meter
Where they differ is this one features the LPD8806 controller IC, which means:
- It works from as low 2.7V (vs the 3.3V of the WS2801)
- It Drives 2 LEDs per segment (means you have to trim them in pairs if you want both functional)
- It offers 21-bit color, rather than the 24 bit color of the WS2801. Still way higher than you could see the difference!
- The documentation for the LPD8806 is more sparse. Even though there are many "interface electronics" to drive the 8806, there are not many places that document the data format & timing.
So if they're so similar, why offer it? Well, we had requests for them locally. And since the fine folks at Adafruit have been already hacking on it, there's been some impressive reverse-engineering of the protocol that has lead to open-source Arduino libraries. Yay!
LPD8806 Stripxel Hard Data
- Rated Voltage: 2.7~ 5.5V
- LEDs: 32 SMD505 RGB per meter
- Color control: 21 bit across 3-channels, 256 brightness levels
- Enclosure: Waterproof silicone tube, IP67 (dust-proof; Protected against immersion between 15cm and 1m depth)
- Enclosure dimensions: 14.5mm (0.57") wide x 4mm (0.16") thick
They come in 5 meter reels and are sold by the meter! If you buy 5m at a time, you'll get full reels. If you buy less than 5m, you'll get a single strip, but it will be a cut piece from a reel which may or may not have a connector on it. You will get 1 mounting tab and 2 screws per each meter you purchase.
Some important links:
- The Adafruit github repository for ongoing refinement of the Arduino libraries. If it's down, get a copy of an archived version from the resources tab. The library also comes with some handy example code to get you up and running right away.
- Stargate Eggbeater. Yeah, cool name, cooler project. They've been spinning on the '8806 too.
- Please Note: Color order of the Green and Blue channels is swapped on the Solarbotics Stripxels compared to Adafruit's, thanks to a customer's input we have a modified library available under the resources tab.
