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&amp;#39;ll have to check its &lt;b&gt;datasheet&lt;/b&gt; for details of what logic
levels it uses!&lt;/p&gt;

&lt;p&gt;
&lt;b&gt;NB:&lt;/b&gt; there are also 3.3V versions of the MAX232
available...&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: 5V to serial convertor</title><link>https://community.arm.com/thread/65888?ContentTypeID=1</link><pubDate>Wed, 15 Sep 2010 07:55:12 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:dcf17a9a-6e36-42c6-a519-e2d58324d465</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
Converting 5V to serial is like converting 10 meters of rope into
100dBA.&lt;/p&gt;

&lt;p&gt;
But if you mean if it is possible to convert 5V logic-level serial
data into RS232-level serial data, the answer is yes. You can use a
MAX232 or similar to convert between the logic levels used by a 5V
microcontroller and the logic levels used by the serial port of a
PC.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
