IMPORTANT
– Because the Pixels use a completely different driver system, the #2-#4 pins are used as simple
grounds when using a string blade. This means that if you want to wire a blade matching crystal chamber, you will
need to use a NeoPixel individual LED wired in parallel with the main blade. Rumble motors are thus not
supported.
Figure 11 – Wiring a back to back style WS2812 blade with two parallel strips. It is also possible to do three strips back to back, which
reduces the vertical shadowing of the blade, but increases the amperage draw. Note that a 0603 resistor on the blade side connector
between 270 to 400ohm should be used.

FULL WIRING
This diagram shows how to wire a recharge port along with accent LEDs and the NECree RGB v2 LED, allowing all
the features of Spark 3™ to be utilized. The recharge port also acts as a kill key, where pushing a kill plug into the
port will stop power from getting to the board.
