RS232 to TTL with DTR input


Hello there,

Does anyone know of a small RS232-TTL converter, with a DTR pin?

Right now I’m using a RS232 Shifter SMD from Sparkfun:
Which works fine. But I also need to access to the DTR (pin 4). And I’m a goofball at soldering, so I’d prefere something premade like the sparkfun.


Check out:

Ron Diol is the owner and if he does not have what you want he will make it. He was very resonably priced and quick turnaround.

I had him make just what you are looking for with a MAX3238 chip.



He certainly got a lot of RS232 stuff. Thx.
