I see in the Pro Mini info that each pin can supply 40mA but what can the regulators on the board supply in total? I am going to have a ChronoDot, 3 leds and 2 - opto channels at 40mA each. Will the Pro Mini 3.3v handle this? Does anyone know of a low current optoisolator most of mine now are 50-80mA. I would love to find a lower current one that I could build a very low current package.
Thanks
