Hi all, I'm making a project with arduino (nano, mini or Uno)that requires low power consumption. I read Nick Gammon's post about: Power saving techniques for microprocessors. After experimenting with arduino Uno, I got similar voltage readings running with the vIn pin and the 5v pin. I also read other posts regarding the topic. (sleep_watchdog_battery, The Shrimp and several more...)
I'll very appreciate it if you can help: 1. When trying the bypass a voltage regulator, for example on the arduino Uno, and connecting a 5v power source to the 5v pin, are the only components consuming power are: the USB chip, LEDs and the atmega chip? 2. Looking at arduino mini and arduino pro mini, Do they consume more power then "the shrimp" or then the Atmega328 processor on its own - the "Bare-bones board" from Nick Gammon's post? If they do, by what components?
From what I understand, the pro mini has a voltage regulator and the mini doesn't, So the pro should consume more than the mini. Am I wrong?
