I'm looking into sound card, but honestly just for color mixing and flicker effects. I'm not all that interested in sound or speakers. I'm also trying to keep my saber quite small.

I note two sizes of Nano Biscotte v4, which has me a bit confused. The MHS Nano Biscotte v4 Assembly (looks much bigger) vs Nano Biscotte v4 Sound Module (looks about half the size).

The item descriptions mention differences in setting up neopixel and pinout order. Is that really all? No advantage to the physically larger card?
