Product Name:
2.4G Wireless Serial Port Transceiver Module RF 2.4G IPEX Antenna UART TTL232 for Arduino MEGA2560 DUE
Packing list:
1 pcs RT39D01 2.4G TTL Wireless Transceiver Module
OR
1 pcs USB to TTL232
OR
Kit
Overview:
RT39D01 is a TTL232 Wireless Transparent Data Transmission Module based on 2.4GHz frequency band, using CI24R1 chip.
The module supports basic AT Commands: Baudrate, Parity bit, ID Number, Version Information, Transmit Power, Frequency Band, Acknowledge Mode and other function settings and queries.
When the module is in AT Mode, the user can use the serial port to send AT Commands to set the parameters of the module.
When the module is in transparent data transmission mode, in ACK mode (default), it can be used as a one-to-one transceiver. If it is applied to one-transmit and multiple-receive (master-slave mode), it needs to be changed to NO-ACK mode through AT command
When the CMD port of the AT module is short-circuited, it enters the AT mode. and when it is disconnected, it is the data transparent transmission mode.
When the module is abnormal, short-circuit the two pins of RES on the board for 5 seconds, then power on again to restore the factory settings

Power supply description:
The transmit current is 50mA (+11dBm); the receive current is 25mA, please use a small ripple power supply
Note: In order to make the module work stably, it is recommended to use a power supply above 8W (5V/2A (recommended to reduce the transmit power), 6V/2A, 7.4V/1.5A, 9V/1A, 12V/1A)
AT command:
Please refer to the AT command manual below

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)
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
}
//----------------------------------------------------------------------//
