From: "Edson Brusque" > I know that (most) PIC ports can sink/source 25mA. The limit varies, some PIC pins can sink more than they can source; often 25mA compared to 20mA. However, this is the per pin limit, the port limit is often much higher (200mA off the top of my 4:35am head). You can combine pins to double the current rating- just make sure you switch both on/off at the same time :) Ben -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
