View source for MAX232 Breakout

==Overview==
This is the RS232 converter breakout that is capable of running at 3V and communicating with 5V logic.It's easy to set up your RS232 to TTL connection using this breakout. The MAX3232 are guaranteed to run at data rates of 120kbps while maintaining RS-232 output levels. And it 
operates at a broader voltage than the 232 (3 - 5.5V) you can use this on both your 3.3 and 5V projects!

==Application==
*Notebook, Subnotebook, and Palmtop Computers
*High-Speed Modems
*Battery-Powered Equipment
*Hand-Held Equipment
*Peripherals
*Printers 

==Examples==
Here is the guide illustrates how to set up the RS232 to TTL connection.

===Arduino Example===
 int val;
 int ledpin=13;
 int i;
 void setup()
 {
  Serial.begin(9600);
  pinMode(ledpin,OUTPUT);
 }
 void loop()
 {
  val=Serial.read();
  if(val=='r')
  { 
    i++;
    digitalWrite(ledpin,HIGH);
    delay(250);
    digitalWrite(ledpin,LOW);
    delay(250);
    Serial.println(i);
  }
 }
