So, I am now the proud owner of a new Nano Biscotte V2 sound card. I am eager to get this baby in a build that has been sitting on my work bench for too long.

I am no expert at this saber smithing yet. The only other sound build I did was made with the Nano Biscotte V1 MWS version. I have read though the postings about the new model and am hoping that someone with a better understanding of electronics can look this over and make sure I interpreted the information right. I plan on using the new version the same way as the old one, WITHOUT FOC. I might tackle that in another build, but not this one.

Thanks in advance for any input, you guys are always a big help.

From the looks of it, it looks right to me. I take it you are using a single die main LED.

Yes. I am using a Rebel Star Green LED.

OK. Just remember to use the proper resistor, and you should be fine.

Yep, I have that, too.

Thank you much for your input.

Now, here we go.................................

Out of curiosity, why a resistor instead of the on-board "drive" parameter?

It's a Rebel green, you can use the drive parameter if you like. Set it to about 950, and it'll be fine. Or leave it running on full and get a little more brightness.

According to The Word of Erv (tm), "Always use a resistor." There are a few exceptions, and single-die cool-color Rebel LEDs with a single li-ion is one of them. You can still use a resistor if you want, and it'll add a small margin of safety to the LED, but it's not necessary in this particular case.

If you change the color of your LED to red or amber, switched to a different brand of LED, used a multi-die LED, or basically any change to the LED, then you'd need a resistor again.

ss is right im using a cyan led on the v2 with no resistor. works great!!
