Just for reference, I recently discovered the ULN2803 8 channel driver chip
that can do about .25A per pin, is cheaper than 8 equivalent transistors,
and has diode protection built in. Plus it's basically one input and one
output per channel, so only a bit more soldering on a breadboard...

Hi All,
Does anyone know how much current a GPIO pin on tmote can supply if

I can't recall what the datasheet says, but I recall being able to
drive 40mA. I was trying to drive some EL-wire, which requ
