WS2811 LED Driver Chip - 1000 Pack
Now available from PMD Way is the WS2811 LED driver IC in packs of one thousand.
Using the WS2811 and your own LED you can make your own addressable LEDs, just like the ones found in popular "NeoPixel" branded LED strips and so on.
The package is surface-mount SOIC-8, not the smallest so you can hand-solder them if you really need to.
Please review the datasheet (link below) for complete information.
