Is there a method to power-off, then close, the FTDI chip ?
The scope is to save some power consuption, using arduino uno rev3.


Otherelse is possible to hot plug and hot unplug a FTDI module from a Arduino Pro mini ?

If not what strategy could I try ?
Using a transistor with a support of an analog port, but in this case I could not power off ADC and ports.

I could use a maxim ic, or what else ?
any suggestion will be appreciated,

Can you spell Google? try here : http://gammon.com.au/forum/?id=11497.. Read the whole thing and follow any other links from that page. It's one of the very best write-ups on power saving I have ever seen.

No.

Maybe...but how would that help?

Using a transistor with a support of an analog port, but in this case I could not power off ADC and ports.

The ADC is powered off using the chip's internal power control register.

See the "power management" section of the datasheet.
