I plugged the FLORA V3 in my computer, and using the Arduino IDE, and the Neopixel  library (https://github.com/adafruit/Adafruit_NeoPixel), I uploaded a first program on it. The connections are simple:

    - Neopixel's IN to Flora's VBATT

    - Neopixel's GND to Flora's GND

    - Neopixel's DATA INPUT to FLORA's 9th pad

I also made a touch sensitivve switch, with two conductive threads.
