RoverWing NeoPixel connector

RoverWing allows connecting a strip of “smart” LEDs, using WS2812b or SK6812 chips. These LEDs, commonly called “NeoPixels”, contain small chips which make them individually addressable: you can independently set colors of different LEDs using just one data line. You can read more about them in Adafruit’s Uberguide: https://learn.adafruit.com/adafruit-neopixel-uberguide. Note that RoverWing only allows the RGB NeoPixels; RGB W NeoPixels, which add white LED to the usual RGB, are not supported.

RoverWing NeoPixel port uses JST PH3 connector, with the same pin order as used by Adafruit’s Hallowing board and some of their NeoPixel strips (clockwise looking from top):

  • Data
  • 5V
  • GND

You can connect up to 128 NeoPixels; note, however, that RoverWing can only provide up to 3.5A currrent for NeoPixels and servos combined. Since each NeoPixel can use up to 60mA, it means that you can not power more than 60 NeoPixels at full power, and that only if you do not use any servos. (It should be noted, though, that 60 mA is absolute maximum - much more typical power consumption is 20 mA).
