SparkFun LuMini LED Ring - 2 Inch (40 x APA102-2020)
COM-14966
This is the two inch version of the SparkFun LuMini LED Ring, packed with 40 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 eight detachable mounting points (four inside the ring and four
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.
