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);
}
}
