Can't use Serial with FT232RL USB to Serial Converter

Hi there,

i am trying to use the FT232RL USB to Serial Converter to upload a sketch to arduino. I installed the FTDI Driver correctly and double checked the wire connections but always when i try uploading a sketch i get the following error:

I really dont know what to do. Im just attaching a picture of the USB to Serial Converter that I am using.

Thanks,
Louis

Should the pin you connected to RESET not be connected to CTS?

I just tried to switch it but it still doesn't work...

Just something to be added: I think the problem is that I'm using the wrong pins. So here just a pic how I got the converter. There was a jumper on RXT and TXT pin.

Where is the "here" picture?

OK, that board appears to be another "orphan" board flogged on the Internet (Aliexpress and DX.com, way over-priced), designed by someone who could read the data sheet but had only a half idea what it all meant.

The "Reset" pin is entirely useless, should never be brought out to a terminal, yet is on a number of these incompetently designed Chinese USB-serial boards. Just cut it off (or de-solder and pull it out) to remind you that it is of no use. :grinning:

Connect a 0.1 µF capacitor between DTR* and the Arduino Pro Mini Reset pin - or in fact just connect DTR* directly to the DTR or "GRN" (not GND!) pin on the Pro Mini which already contains this capacitor.

Note that RXD and TXD need to be crossed over between your interface board and the Arduino. VCCIO on your module should not be connected to the Arduino.
