LattePanda RS232扩展板

Introduction

This industrial-grade RS232 shield from DFRobot is specially designed to expand 1-way RS232 interface(D-Sub, 9Pin, male) for LattePanda V1.0. Adopting MORNSUN RS232 module, the product comes with power isolation and signal isolation, and the onboard DB9 connector (male) allows easy connection with other RS232 devices. Besides that, there is an adapter contained in the package for your convenience. The product employs a stackable connection, which makes it able to be easily fixed onto LattePanda mainboard by copper columns without blocking the heat dissipation area of mainboard. This RS232 Connector Expansion Shield can be safely applied in industrial scenarios.

Connection

Sample Code

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
  while(!Serial);
}

void loop() {
  // put your main code here, to run repeatedly:
  if(Serial.available()>0){
    char a;
    a = Serial.read()+1;
    Serial.print(a); //return all the data that received from LP
  }
}

Burn the codes into your Arduino Board.

Expected Results

Open the LattePanda serial Monitor, select COM1, and set baud rate to 115200. Send data to Arduino, then it will return after plus 1.
