Thanks so much for the suggestions!.
I've changed the nrf module with another one and now I've got 4.60uA in sleep... now I'm very satisfied!

Ciao Gianluca

thanks very much for the quick replys. I will try to exchange the radio module (now it is soldered to the arduino with some spare wires I have).
I'll let you know.

Hello to everyone!
I need some info about a compatible mini pro arduino board (3.3v 8mhz).
Removing the power led and removing the power regulator I get power consumption in the uA area. But if I connect the nrf24 when it goes to sleep it consumes around 1.21 mA. The nrf24 is "untouched": I've only added the 470uF capacitor.

Do you know what I can do to get in the uA area with the nrf attached?

Thanks!
Gianluca
