The Arduino as a Serial Adapter

If you don't have any USB to Serial adapter you can use your Arduino (Arduino-Uno or older) for that purpose. After removeing the chip on the board connect the pins like seen on the picture:

  • +5V to +5V
  • Ground to Ground
  • Pin1 to DTR
  • RX to RX
  • TX to TX
