Then I cut a PCB trace to isolate the regulator and power LED, as shown below. With this small modification, I could get the current draw down to <3uA (which is the error of my meter). (via Arduino mini, pro mini power consumption - Arduino Forum)
Arduino Pro-MiniをパワーLEDパターンカットして電力消費を3μA以下に?!ここまでやるか!
