When do you need 5 volts on the gumstix basic 400bt with tweener board vs 4volts? Does using 5v help when adding other devices to the GPIO lines, or give slightly more distance on the bluetooth connection? Glenn Mossy gm...@ya... |

I believe that the only time that the 5v wall-wart is when you're using a robostix, or roboaudiostix (althought the roboaudiostix doesn't have the power jack connector). -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

Higher input voltages just generate more heat. Regards, Ken |
