Data Sheet

WS2812B LED
Intelligent control LED integrated light source
9/9
electric soldering iron’s temperature being not higher than 350
℃
, every time when
welding electric iron in the bracket pin,stay time shall be no more than 3 seconds,if
requiring repeat welding,then interval time shall be no less than 2 seconds.Please don’t
touch or extrusion the LED’s surface,in order to avoid damage to the internal LED, at the
same time, please pay attention to avoid the electric iron burns the colloid on the surface of
LED and other injuries.
