I want to program the Robotdyn Mega 2560 PRO MINI which has no USB port.

How do I connect the pins to an FTDI?

Which setting do I have to use in the Arduino IDE?

Connect the Arduino to the FTDI in the following way:

  • FTDI - Arduino
  • VCC - VCC
  • GND - GND
  • RX - TXD
  • TX - RXD
  • DTR - 100nf capacitor - RST
  • CTS is not connected

Use the following settings in the Arduino IDE

  • Board: Arduino/Genuino Mega or Mega 2560
  • Processor: ATMega2560 (Mega 2560)

Arduino with FTDI

The image shows the Arduino with colored connectors and with 4 extra rows of connectors. These are not part of the original Arduino. I added them to make it easy to connect lots of I2C devices for testing.
