Ft232rl application in a circuit

Other Hardware 3rd Party Boards

Hey.

First off, i hope this is posted in the right category.

So i want to integrate a USB-Serial Bridge (a ft232rl chip) into my project.
My project is a RGB-LED matrix with ws2812b leds.
Here is my EasyEDA schematic. It is not complete yet!

It would be nice if someone could have a look at the schematic as well as the project desciption.

I had a look at the according datasheet but couldt find the right applecation on how to use this chip for my needs.

For exapmle what do the cts and rts pins do?

Thanks for any answers!

They are RS232 hardware handshaking signals for flow control. See:

Have a look at the schematic of the Nano; it uses a FT232 and should show you how it can / should be used.

With regards to RTS/CTS and other signals, you can read up on RS232 handshake.

Alright tahnks for the answer!

So the RTS/CTS pins are only for a rs232 converter i guess.
I had a look at the nano schematic and it seems pretty simple.
only difference beeing the atmega chip running on 5v not 3.3.
So VCCIO should go to 3.3v otherwise i would kill my esp8266 right?
