[quote:29ec16aff2="Vincent"]I have a Mosfet 2N7002 that consumme power.[/quote:29ec16aff2]
A mosfet doesn't consume power, if it's off.
[quote:29ec16aff2]And on the RX and TX line I have a emitter and receiver that consume too. And I have I2C device too with pull up resistor that consume power.[/quote:29ec16aff2]
If the additional ic's don't consume much power, on can supply them via an output pin, or use another transistor to kill their supply line.
