Completed the first board of the 2nd revision. The 3rd revision has some minor changes, more suitable footprints and better locations for parts. This one works nicely too. Total power consumption is about 6mA - with the LED on (powered by the pull-up). So far the only power-relevant code shuts off the analog comparator. Maybe the ADC should go to sleep as well.
