I'm using a usb powered Arduino nano and a PN2222 transisitor to turn on/off an Intel Galileo board. This is the circuit I’m using (replacing the motor with the Galileo).
However, there is a voltage drop across the transistor and the Galileo board is not getting enough voltage to operate correctly.
Eventually, I need to battery power the nano on the Vin and Ground pins.
IS there a way to output more than 5 volt from the nano? Or could I use another setup to act as a switch?
