Hello
Can anyone, please, tell me how to use 5V servos
with axon mote that operates on 3.3V?
Thanks, in advance.

You use separate power supply :)
-
Or use a voltage divider to reduce it to the required voltage.

One really nice guy 'palmisano' already answered this question (on you-tube):
"The Axon Mote has regulated (3.3V) and unregulated (battery voltage) power buses. You hook up the servo to the unregulated power bus. Servos work with any PWM signal above 3V."
Thank you palmisano.

Hi,

He also made the board, so he's in this for the money. Nice? I don't know about that :D

The servo can be powered independently ,it only needs the signal from the micro controller, make sure the ground of the signal and the ground of the power supply are common
