Neopixel lightsabers utilize the individually addressable RGB LEDs mounted in a strip inside the blade. These Neopixel LEDs are controlled by a microcontroller that can manipulate them to produce a range of colors and effects.
In addition to the LEDs, Neopixel lightsabers also feature a built-in soundboard that can generate a wide range of sound effects and audio files. The soundboard is usually pre-loaded with several sound fonts you can choose — and you can customize your own using our Obsidian software on your computer.
To power the Neopixel blade and soundboard, the lightsaber includes a Li-Ion battery pack that is stored in the hilt. You can opt for rechargeable batteries and decide if you want an external recharge port connector. The battery pack can be charged using a micro USB cable and charger, similar to a smartphone or other electronic device.
