The Adafruit FLORA V2 is their latest wearable Arduino compatible microcontroller board and it features a programmable NeoPixel for added blinkiness. They have put a lot of thought into this board, with a 2A power FET attached to the tiny on-off switch, a 3.3V regulator with protection diode and USB fuses. It can drive up 50 NeoPixels using the onboard supply or up to 500 with an external 5V source. You can program it either via Adafruit's version of the Arduino IDE or with Arduino IDE version 1.6.4+ with a little tweaking to install FLORA support.

Adafruit supply a comprehensive getting started guide for FLORA and an Arduino IDE 1.6.4 guide .
