Datasheet

16 NeoPixel Ring (http://adafru.it/1463) —
1.75 inch (44.5 mm) outside diameter. Max
5V @ 1A.
24 NeoPixel Ring (http://adafru.it/1586) —
2.6 inch (66 mm) outside diameter. Max 5V
@ 1.4A
8x8 NeoMatrix (http://adafru.it/1487) — 64
LEDs total. The pixel spacing and board size
allow seamless tiling. Max 5V @ 4A.
NeoPixel Shield for
Arduino (http://adafru.it/1430) — 5x8
matrix plugs directly atop an Arduino board
(can also be tiled separately if desired). If the
overall brightness is carefully limited, can be
directly powered from the Arduino. For most
situations, connecting an external power
supply is recommended. Max 5V @ 2.4A
(the Arduino can only supply about 500
milliamps).
NeoPixel Stick (http://adafru.it/1426) — 8
NeoPixel LEDs on a rigid circuit board
packed even more tightly than the flex strips.
Solder pads on the back for connecting wires
or breadboard pins (not included).
Current ratings shown are approximate maximums
(all pixels on at peak brightness). Mixed colors and
lower brightness settings will use proportionally less
power.
