Product Name:  Arduiuo UNO MEGA2560 RF kit 2.4G Serial ports Wireless Transceiver Module 5V 3.3V TTL232 for Internet of thing DR Radio APM APM2
 
 
 
Packing list:
2 pcs 2.4G 100mw RS232(TTL Lever) Wireless Transceiver Module
1 pcs  USB to TTL 232 (Ch340 IC)
1 pcs 5pins female to female dupont wire;
 
 
Overview:
   
The transceiver module  is based on 2.4GHz frequency band wireless transparent data-transmission module.
This Module supports most basic AT commands: baud rate, ID number, frequency settings and inquiries; factory settings; version information.
When the module is in AT module, users can use serial-port to issue AT commands to set the module's parameters.
When the module is in transparent data transfer mode, the user transmit data, frame number data module, add packaged rowcount, and then automatically transmit , at reliable range, the module will automatically re-transmit data to ensure successful transmission.

ARDUIUO IDE Serial data Transceiver:
 
 
Copy the following code:
//----------------------------------------------------------------------//
 
// Pin 13 has an LED connected on most ARDUIUO boards.
int led = 13;
 
String comdata = "";
 
void setup()
{
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
Serial.begin(9600);
Serial.println("Hello, I am Arduiuo!");
}
 
//Serial data transceiver
void loop()
{
while (Serial.available() > 0)
{
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
comdata = char(Serial.read());
delay(2);
}
 
if (comdata.length() > 0)
{
Serial.println(comdata);
comdata = "";
}
 
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
}
