SK6812MINI LEDs (10 pack)
At just 3.5x3.5mm, these are the smallest digital LEDs around! Though their size may be diminutive, they're no slouch, and pack a SK6812 driver chip and RGB LEDs into the tiny package. We can think of lots of things to do with these, from making super lightweight LED jewelry to the densest LED displays yet.
Check out the datasheet.
We also carry these preassembled in strip form.
