Hello: Can I use my ARM CORTEX MO board to contert 5V to serial? will it be reliable? anyone already experienced it? can we interface them directly to a microcontroller without other components?
thanks
The particular Cortex-M0 microcontroller was not mentioned - so you'll have to check its datasheet for details of what logic levels it uses!
NB: there are also 3.3V versions of the MAX232 available...
