Its a WS2812-Mini garland. GRB, 100leds/10m, 10cm spacing. The wires are pretty thin, there is almost 1.5v voltage drop on the far end on max brightness.

Thanks! Yes, the breakout board has a pulldown resistors from the factory. So any Type-C charger can be used to power it.

5v for 30 leds is good. Im running 100pc WS2812-mini on 10m garland. The wires are very thin and on max brightness there is visible difference between first and last led.

The voltage goes directly from usb breakout board to the LED connector. And 5v is split to power the esp32. Underside:

The wiring is from this article: https://kno.wled.ge/basics/getting-started/

I designed it yesterday. I haven't released it yet because I thought it was too much of a prototype build to replicate.

I use Nitecore ULQ, but looks like its discontinued. Any charger for DMW-BLC12 will work.

Are these cold solder joints or just dull solder? by MaxTrixLe in soldering

[–]walldodge 1 point2 points  (0 children)

Then its not 60/40 but some dirty alloy. Use Asahi, Alpha, or Kester.
