SN Pixel and Xenopixel are advanced lightsaber technologies commonly used in custom and replica lightsabers. They enhance the visual and sound experience by utilizing neopixel blades, which have hundreds of individual LEDs built inside the blade, this is why they can make crazy effects, super bright, just like a real lightsaber would look! All Neopixel Sabers are fitted with a LXR3 speaker- the ultimate speaker made purposely for Lightsabers. - Between the two boards the only difference is SN Pixel uses 'real voice inspired' sound fonts!
