Deep Sleep

Is deep sleep still possible on the 3.9? I haven’t heard a lot about it, and I know that the low-voltage switch is no longer something that can be done on the 3.9, so I’m curious if deep sleep is still in the works or not.

Yes. it hasn’t been a high priority for me since the standby power is usually very good, but it’s still my intent to make it happen.

It’s still possible, but requires an external FET, same as on the V2 boards.

Well it’s good that it’s still possible. I’m excited for it, especially for hilts too tiny for kill switches that are a pain to swap batteries, like the child hilt.
