Overview

Assembly

Please refer to the Enchant Prop FX Board product page for assembling the Enchant Prop FX Board and Teensy.

Pin Input/Output

Wiring

The brown wire is optional, but prefer for stability.

Buttons

The Lightsaber software will use 2 buttons: Power and Aux. They are mapped to the following pins:

• Teensy Pin 13 -> Power
• Teensy Pin 18 -> Aux

Connect one terminal of the button to the pin indicated and the other to BAT-.

Battery

It is very important to select a high drain battery (or 2 batteries in parallel providing the equivalent high drain), for reasons of maximizing blade brightness as well as stability during audio playback.

Connect the battery directly to both BAT+ pins when possible for additional stability. Use at least 26 gauge thickness wire.

USB battery charger note: The on board battery charger uses a safety timer of 1-5 hours. This is usually not an issue for a setup using a single 18650 battery. However, bringing a deeply depleted battery back to full charge, or to fully charge multiple batteries connected in parallel, will require the charger to be unplugged and plugged back in to reset the timer.

Unprotected battery note: Ideally a PCB protected high discharge battery should be used. However unprotected batteries will often offer better discharge ratings. It is okay to use an unprotected battery as long as precautions are taken so that the battery does not discharge below 3V. For example: The Enchant Prop FX board will stop functioning at some point after the battery voltage drops below 3.3V. This may happen before the board gives the instruction to turn the LEDs off, leaving the LEDs on, continuing to discharge the battery. It is important to recognize when this happens and manually unplug the blade to prevent continued discharge of the battery.

Kill Switch note: The software will utilize hibernate mode for minimal battery drain while the Prop is “off”, so a kill switch is not necessary for the usual use case.
