Hi,

I've removed the same parts that you have mentioned. My results are a little different. Just thought I'd post results here if anyone is planning on doing the same thing.

  1. Without removing anything, the nano at 5v supplied to the 5v pin uses 22ma.

  2. Without removing anything and putting it in to sleep mode using the following function, I get 10ma at 5v
    LowPower.powerDown(SLEEP_8S, ADC_OFF, BOD_OFF);
    The library I used: GitHub - rocketscream/Low-Power: Low Power Library for Arduino

  3. After removing the voltage regulator (I didn't desolder it, I just cut it off with edge cutters) and putting it into sleep mode as per point 2, I get 3.6ma at 5v

  4. After removing the power led, again I did not desolder the led, I just cut it off with edge cutters.
    I get 0.23ma in sleep mode.
