The SparkFun Lumenati 3×3 is a compact LED board featuring nine APA102C addressable RGB LEDs arranged in a 3×3 array. It can be daisy-chained with other Lumenati boards to create larger custom LED formations, and the 0.1" (2.54 mm) pin spacing allows direct installation into a breadboard for prototyping.

The APA102C LEDs use a 2-wire SPI-like protocol (clock + data) rather than the single-wire timing-critical protocol used by WS2812B LEDs. This makes them compatible with single-board computers like the Raspberry Pi that don't natively support precisely timed data streams. Each LED on the board is numbered to indicate its position in the chain, simplifying code development.
