  1. Disable the processor. The best option is to remove the processor from the board (with the power removed). If you cannot or would prefer not to remove the processor, connect a jumper wire between RESET and GND. This will hold the processor in reset preventing it from running.

  2. Jumper TX to RX.

  3. Apply power to the board.

  4. Start your favourite terminal application. Serial Monitor will work fine.

  5. Ensure your terminal application is connected to the correct serial port. The baud rate is irrelevant.

  6. Type. As you type, the characters should be echoed to the screen.
