USB to Serial (RS232) Adapter
These day’s most computers and laptops don’t have the RS232 port installed so if you can only connect something trough RS232 you’re looking at a problem. This project comes in handy, and gets you out of the problem. It’s really simple, few parts are involved and if you do it with SMD parts it can be pretty small(like in the picture).

Hi,
This little adapter has awakened my curiosity.
I want definitely make this thing.
Except, the info on this page is quite small. No tons of pages are filled with useful information on how to build this.
Can someone please give me a link or a quite ‘easy’ to follow guide with all the step to create this. This would be so helpful.
Also a more detailed picture of the print board would help.
Thank you in advance.

Is it a 33ohm resistor? does this adapter require software drivers?

33 ohm yes, and yes it requiers software drivers you can download them from chip manufacturers website

Thanx!!
one more thing. I can see TX and RX but what other pins of the FT232R connect to the RS232 connector?

nothing else, just what’s on the schematic

Has anyone measure the voltage of Tx and Rx ??
Is it +/-5 or +/-12 Volts??
I ask because some adapters dont meet EIA/RS232 standards.

Has anyone measure the voltage of serial Tx (FT232R pin 1)and serial Rx (FT232R pin 5)??
Is it +/-5 or +/-12 Volts??
