Spectacle Light Board
 DEV-1405 2
tl;dr
1. If more than approximately 10 pixels will be on at once, we
recommend powering the Light Board through the onboard micro-B
USB port.
2. For smaller numbers of pixels, it is possible to power them directly
over the Spectacle control cable.
3. Most of the LED effects want a continuous type signal, such as the
Button board "Latch On/Latch Off" function.
4. Only WS2812 (NeoPixel) type addressable LED strips will work with
the Spectacle Light Board.
Meet the Spectacle Light Board
Designed to make it easy to add relatively complex lighting effects to your
Spectacle projects, the Spectacle Light Board integrates with the rest of the
Spectacle ecosystem to allow you to control lighting effects relatively
effortlessly.
It has two 1/8" (3.5mm) jacks for Spectacle control signals. Pay attention
to the directionality of the jacks! The one labeled "In" should be plugged
into a board that is closer to the Director Board than the Light Board is, or
into the Director Board itself.
The Light Board supports up to three strands of addressable LEDs. Each
strand can have up to 60 individual pixels. Not all types of addressable
LEDs are compatible with the Spectacle Light Board. If you have
questions about whether or not a particular type of LED strip is compatible
with the Light Board, contact SparkFun technical support.
