Was thinking of using the FT231X or FT230X instead of the FT232R for USB-UART connection since it's almost %50 cheaper. Anything I should know before using the new chip?

Graynomad: Short answer, AFAIK there's no reason not to use them. I've just laid out aboard with the FT232R but am thinking of changing it to use the 230X........ EDIT: Another difference, nobody seems to have stock of the 230X. That's a worry if this is a product. Rob I agree with Rob....you…

Actually, you might want to try to find the FT230X at Mouser Electronics ( mouser.com ) because they have an extremely wide variety of components.

Well, I see now that the 230X has no DTR, only CTS... the 231X has DTR

Good point Lefty, the 230 only has RTS, that used to be OK for auto reset I think but I'm not sure these days. The 231 has all the signals so presumably it will toggle DTR in the same way as the 232 does. you might want to try to find the FT230X at Mouser Electronics I just did an Octopart searc…

(some redundancy here) The Duemilanove used RTS thru a resistor (which was not installed) or DTR thru a cap to create a reset. arduino-duemilanove-schematic.pdf 47.36 KB If RTS is still output, it would seem that the FT230X could work. DS_FT230X.p…

I'll go with the 231X. Where can I download its EagleCad part? The latest version has only 232 and 230...

Im not sure, but try http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en537026&redirects=cad

If the site I suggested does not work, I do not have a clue on where else to go....We might have to do some research on it.

Make your own part. Don't ask me how though because I don't use Eagle, but it's usually a pretty easy procedure with these programs...oh hang on, we're talking about Eagle here :slight_smile: Rob

Can I replace the FT232R with FT231X/FT230X?

Sorry about that! At least it will work.ß
