Thank you very much for your answer!

In the next couple of weeks, I will start to do some measurements, and see how how much current the Pro Micro consumes when in sleep mode 🙂

Thank you. This does indeed work!

A couple of questions to clarify:
1) Why does one need to detach the USB connection? Why isn’t it enough to simple attach it again – especially when you then see that the default detach method is empty?

2) If I in my final design does not need the USB connection, should I then detach it anyway (e.g. in the Setup routine) to minimize sleep current?

3) Will Serial1 be working, or should that also be detach / attach – if so, do you also know the command for that?

4) Where is the different sleep modes in your library described (powerDown, idle, etc.)?

5) Can I do anything else (software-wise) to save power in sleep mode, than just calling:
LowPower.powerDown(SLEEP_FOREVER, ADC_OFF, BOD_OFF);

Thank you for your help! I really appreciate your time and your library.
