DIYmall 16bits WS2812B RGB LED Ring

These things are great. I use them in test fixtures on production lines to indicate pass/fail, go/no-go. They're very bright, easy to work with, and good quality. I've been through several packs of these and have only had one that I had to resolder one led on.

Very nice little RGB LED Rings. Use them in many projects no problems. Will purchase again.

Tested all 5 and they work great! They're all very consistent with one another; none are brighter or dimmer than the others and they're all very bright at full brightness. They seem to have a very sturdy build which I appreciate. I'll be buying more of these in the future when I need more.

I'm using an attiny88 to control these for lamps for my grandkids. They are plenty bright and I can control each pixel easily. You might need a 300-400 ohm resistor on the signal wire, but I opted to not do that due to space. I've ran them for a few hours in testing and programming and at full brightness they only got a little warm. I turned down the brightness a bit in the code to hopefully make them last a bit longer.

Individually addressable, wide color range, bright colors. These are beautiful! Place behind a diffuser (scuffed plastic) for better effect.

Estamos hablando que con solo aro con esos 16 led, iluminan de forma excelente, yo lo estoy utilizando en un proyecto con la placa base ESP32 y la compatibilidad es 100%

The solder pads are randomly placed rather than in a row. Weird.

These are small and not floppy, so they are easier to put in a kit of components for a Raspberry Pi class than a strip. The calculations I have seen are that you can drive 12 LEDs at full brightness, so it's unlikely that students will fry the Pi if they are even a little bit careful. They like to make lights chase around the circle. It's a good way to learn about loops and nested loops.

他のものに比べハンダのノリは良くなった。

16個とあるので16個届くのかな？と思ったのですが、実際に届くのは5個です。商品詳細の方には5個と書いてあるので、嘘ではないですね。きっと見出しの16個というのは、LEDが16個ということなのでしょう。この手口は他の色々なものにも応用できそうですね。勉強になりました。
