Hello,

I would like to connect my UM7 to an RS232 port. Does anyone know of a good converter that will work with the UM7?

I found this but am unsure about it:

That should probably work. We’ve used this device from Sparkfun with great success:

Not a problem. You can power the Sparkfun board with the 3.3V output from the UM7 to set the logic level. (That was actually the original motive for including a 3.3V output, actually).
