As an example: ABS plastic contains styrene PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP) electrolytic capacitors can contain Ethylene glycol Brass can contain Lead flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA) Aluminum alloys can contain Chromium To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching! |

Works very well but check color sequence | |
| These work very well when driven by the Arduino NeoPixel library software. Color and brightness of each LED is controlled by 3 integer values one for each primary color with a range of 0-255. Thats 16777214 colors plus black and white. The LED chips are super-bright type and 255 equates to about 20mA per chip which is VERY bright! Using 25-50 is plenty for direct viewing of the diffused LED. I noticed two anomalies with the units I received: 1] When power is first applied, the Blue chip turns on at full brightness until my software begins to run. 2] Red and Green data is swapped from what the included spec sheet describes. Other useful info: A] LEDs self-refresh at approx 278Hz. Multiple LEDs are not synchronized. B] Brightness is controlled by internal PWM. Peak current is ~64mA regardless of the brightness settings except zero. | ||
