## Description

The SparkFun LuMini LED Ring (2 Inch) features 40 individually addressable APA102-2020 RGB LEDs in a compact ring form factor. Each LED can produce over 16 million colours, and the miniaturised 2 mm × 2 mm package allows for tight pixel density and a near-continuous ring of colour. The ring is controlled via SPI (data + clock) through solder pads on the back of the board. Multiple rings can be daisy-chained by connecting the data/clock output of one to the input of the next. Eight detachable mounting tabs (four inside, four outside) can be used to secure the ring or broken off for more complex designs. Key Features 40× APA102-2020 LEDs – Individually addressable RGB with 16 million colours 2 mm × 2 mm LED Package – High pixel density for smooth colour transitions SPI Control – Separate data and clock lines for reliable communication Chainable – Data/clock output pads for daisy-chaining multiple rings Detachable Mounting Tabs – 8 breakaway mounting points for flexible installation 5 V Operation – Powered via solder pads on the back Specifications LED Count – 40 LED Type – APA102-2020 (2 mm × 2 mm) Ring Diameter – 2 inches (~51 mm) Operating Voltage – 5 V Interface – SPI (data + clock) Tip: For larger installations, add a 4.7 µF decoupling capacitor between power and ground to prevent voltage dips when many LEDs are turned on simultaneously.
