3.3. TRUDRIVE™ SEPARATION
Spark 3™ will come by default with the TruDrive™ attached to the main board. If it is desired to have the TruDrive™
separate from the main board for the install, then you can detach the two boards.
To separate them, place a mouse pad at the edge of a table, and place Spark 3™ on the pad with the seam where
TruDrive™ meets Spark right at the edge of the table, so that the entire TruDrive™ is off the table and the entire
Spark™ is on the mouse pad. Then with one palm press and hold Spark™ to the pad, and gently use your other
hand to press the other board until it starts to snap. Then simply wiggle the TruDrive™ back and forth until it
comes free.
It is important to note that once the board has been removed it cannot go back on; plan accordingly before
separating the boards.

4. WIRING DIAGRAMS

The following diagrams are the most common to get your board up and running.
Note: It is very important that the correct resistor be used between the negative pad of the LED and C1-, C2-, and
C3- to prevent burning out the LED for warm color LEDs. For Rebel LEDs if a red, red-orange or amber LED is used,
then a 1ohm 1watt resister is needed. For any other Rebel colors a resistor is not needed. The STTH2L06 diode can
be used in place of the resistor and it is a slightly smaller part.

BASIC WIRING

This is the most basic wiring that is possible to get the board up and running. It is great for testing your Spark 3™
on the bench, or if you are doing a simple install into a saber that will have a removable battery.

Description
Holds the Spark 3™ SD card. Ensure the card is fully inserted
before applying power to Spark 3™.
Driving board that can power two high-power LEDs from Spark
3™. On Spark 3™ only the first three Pads are available.
Hook power and ground from a 3.7v Li-ion pack here.
Hook a 1.5-2.0w, 8ohm speaker here.
Used to power all three of the accent LEDs. Optionally,
additional static LEDs can be powered from this pad. The
output is 3.3v, and it is rated at 200mA.
Each pad can hold one 20mA accent LED. These LEDs will be
sequenced by the chosen pattern.
Pads that hook the TruDrive™ board to the Spark 3™ main
board. Pad #4 is not used.
Hook the main LED and flash LED cathodes to these pads.
Pads for the switches. MAIN can be a momentary or latching,
aux must be a momentary. Make sure to select the correct
type of switch for MAIN in the Config Editor.
