but it's more than just a servo

2014 we now have an R3 update to this design - we now have a stacking header for the ICSP 2x3 pins and breakout the SCL and SDA pins

to calculate the power

Adafruit DotStar Digital LED Strip - Black 144 LED/m - 0.5 Meter Development Tools and very readable due toThese fancy DotStar LED strips are a great upgrade for people who have loved and used NeoPixel strips for a few years but want something even better. DotStar LEDs use generic 2 wire SPI, so you can push data much faster than with the NeoPixel 800 KHz protocol and there's no specific timing required. They also have much higher PWM refresh rates, so you can do Persistence of Vision (POV) and have less flickering, particularly at low brightness levels.
