I see them advertised as USB to TTL converters, but then when I read more about them, I find that they are USB to RS232 converters.
Isn't there a difference between TTL and RS232 voltages?
Wouldn't the output from a microcontroller need to be converted to RS232 first, before one of those advertised USB converters could be used?
Is there a way to directly convert from a microcontroller output to USB?
Thank you
Pat
