Figure 9 – Single color cross-guard wiring. This is almost the same as Spark 2™, the only difference being that the second group is controlled
from C4 instead of C2. Note that a resistor or STTH2L06 diode would be needed for each die if the blade color is red or amber.
The same as with X-Saber, for each colorset that utilizes this feature c4 needs to be set appropriately in the color
set to a non-zero value.

WS2812 WIRING
NEW IN R3
. Spark 2™ now supports WS2812 strip blades! Wiring them has change a bit since the initial release, so
pay attention to the diagram below.
Notice that a resistor that is somewhere between 270ohm to 400ohm is required. It doesn’t really matter what the
value is, it’s just there to protect the data line. I usually use a 330ohm as it is a pretty common value.
Also, this example is using the triangular prism style, where three strips are wired in parallel. To save power it is
possible to just do two strips back to back, though I’ve found this increases the unsightly vertical shadowing. To do
this wiring one strip can simply be omitted since these are just in parallel wiring.
Finally, it is extremely important to use a 10amp battery with this type of blade as it does tend to draw a lot of
amperage.
