    I'm planning on led modding my nds lite but I need to figure out what resistors to use.

    Thanks!

    If you grab Vcc at the GBA slot you get about 3.5v nominally. I've put some LEDs in mine, used 3.5v blue surface-mount LEDs that draw 10mA each. I put three of them in, and haven't noticed any change in battery drain. I did not use any resistors at all, just wired them directly from Vcc and ground.

    I think the voltage from the battery is the standard 3.7v you get from a l-ion

    battery is 3.7v
    gba cartridge is 3.3v
    charging connector is 5v

    you are probably best off taking it off the gba cartridge connector since that is a regulated supply.
