SparkFun LuMini LED Ring - 1 Inch (20 x APA102-2020)

COM-14967

This is the one inch version of the SparkFun LuMini LED Ring, packed with 20 individually

addressable LEDs, each capable of producing 16 million colors, it provides you with a lot of color for

just about any reason! LuMini is a miniaturized version of our Lumenati LED line but instead of

utilizing 5mm by 5mm APA102 LEDs (APA102-5050), LuMini uses a 2mm by 2mm package

(APA102-2020). This allows for incredibly tight pixel densities, and thus, a more continuous ring of

color for you to use!

The LuMini LED Ring is powered and controlled using a few solder pads on the back of each board.

These pads include 5V and ground, a set of pads for data and clock input, and another set for data

and clock output. Since the ring acts like a string of LEDs, you’ll find multiple numbers silked onto

the back of the board that correspond to the LED number in the above. The last handy feature we’ve

equipped the LuMini LED Ring with is four detachable mounting points (two inside the ring and two

outside) that can be used to secure your ring to a surface/project or be broken off to make more

complex designs.

Note: In larger installations you may need to add a decoupling capacitor between power and ground

to prevent voltage dips when turning on a whole bunch of LED’s simultaneously. We recommend

using a 4.7µF capacitor which we sell in strips of 10.
