I want to use the Arduino Nano with a 9v battery as a power supply. I was looking at the Nano spec page and i saw this
"The FTDI FT232RL chip on the Nano is only powered if the board is being powered over USB. As a result, when running on external (non-USB) power, the 3.3V output (which is supplied by the FTDI chip) is not available and the RX and TX LEDs will flicker if digital pins 0 or 1 are high. "
Is there a way I can still get the 3.3v output using the 9v battery?
