The best that can do is 500mA without a heat sink,. > I'm a bit tight for time (going home, leaving this BBB running on our boat) so I've reduced the input voltage to the 7805 from raw battery voltage which is about 14 volts down to 9 volts (which I need for various other devices). Thus the 7805 will be dissapating much less power now - (4 x current) watts as opposed to (9 x current) watts. -- Chris Green ยท -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
