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)
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.
