Hello Everybody.
I would like to ask a question regarding serial ports on a board.
I am reading the specs of one in particular and it says:
CON2 Serial Interface RS232C
CON3 Serial Interface 3.3V CMOS
among others (USB, etc)
Now I know that RS232 is the standard for serial ports but what do they mean by 3.3V CMOS?
I ve never heard a type of serial port named like this. Anyone can enlighten me about this?
Thousand thanks in advance
