Below item is powered by Canton-electronics Ltd . Product Name: 20dBm 2.4G Wireless RF Data Transceiver Module UART RS232 TTL232 for Arduino MCU Module No.: TB387Packing list:
1 pcs 2.4G Serial portWireless Transceiver Module; 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.Performance Parameter: Working voltage: 3.3V-5.5V;RS232 Interface ( 3.3V/5V TTL level)Frequency range: 2402~2482MHzTransmit power: 20dBm;Receiver sensitivity: -87dBm;Operating temperature: -40~+85 ° c;Transparent transmission mode baud mode configured baud rate fix is: 9600;Pinout :1, VDD:3.3V or 5V power supply ;2, GND: Power Ground;3, TXD: serial port output, Arduino or USB to serial port RXD;4, RXD: serial port input, Arduino or USB to serial port TXD;5, CMD: Enter PIN AT mode, active low level; Data Sheet : Please contact seller on message ; Typical applications： 2402-2482MHz ISM/SRD band systemsConsumer electronicsAccess control, Attendance, LogisticsSmart FurnitureRobertWireless sensor Wireless communication between Arduino and PC(Also application with other 3.3V/5V level MCU ，for example: FPGA CPLD STM32 C8051 PIC AVR MSP430)for this Applications you need: 2pcs 2.4G Serial port Wireless Transceiver Module; 1 pcs USB to ttl cable; Arduino UNO/MEGA2560
ARDUINO Serial data transceiver： Copy the following code： // Pin 13 has an LED connected on most Arduino 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 Arduino!\");}//Serial data transceivervoid 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 ★Introduction for Shenzhen Canton-electronics Trading Co.,Ltd :
