The GM862 documentation does not seem to specify the current available on the GPIO pins.
Would it be safe to connect a low current LED directly to a GPIO pin and ground via a resistor.
I am considering using a [10 ohm resistor with a [forward voltage 2.5v, forward current 30mA LED.](http://www.maplin.co.uk/module.aspx?ITAG=FAQ&ModuleNo=25550)](http://led.linear1.org/1led.wiz?VS=2.8;VF=2.5;ID=30)
