Product Description

Product Name:2x UART RF Wireless Transceiver Module + USB to TTL RS232 Telemetry Kit 2.4G for Ardiuno 3DR Radio APM APM2 Vehicle UNO DUE MEGA
Module No.: TB395
Packing list:
2 pcs 2.4G RS232(TTL Lever) Wireless Transceiver Module
2 pcs 2.4G IPEX Antenna
1 pcs USB to RS232(TTL Level), IC Ch340
Overview:
TB387 is based on 2.4GHz frequency band wireless transparent data-transmission module.
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.

Application example:
Wireless communication between Ardiuno and PC(Also application with other 3.3V/5V level MCU ,for example: APM APM2 Raspberry pi FPGA CPLD STM32 C8051 PIC AVR MSP430)
ARDIUNO IDE Serial data Transceiver:
Copy the following code:
//———————————————————————-//
// Pin 13 has an LED connected on most Ardiuno 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 Ardiuno!”);
}
//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
}
