Figure 7 - Wiring with an RGB crystal chamber. This will have an RGB led that matches the blade color and pulses with the blade. Note that
all three pins of the REB LED have a resistor since power is coming from the battery. I recommend a 22-33ohm for R1, and a 1ohm each for
R2.

RUMBLE MOTOR WIRING
When not using a 4
th
die the C4 pin can be used to run an accessory, such as a rumble motor or another special
accent LED.
The following diagram shows the use of a low power (3.3v) shaft-less motor that can be purchased from Pololu
. If using something that requires more voltage than 3.3v, the power could be drawn directly from the battery
instead of the VLED+ pin.
