2.4G Multi functional Interface TTL RS232 RS485 TYPE-C USB for Arduiuo NodeMCU ESP8266 ESP32 Modbus RTU (TTL Transceiver)

2.4G Multi functional Interface TTL RS232 RS485 TYPE-C USB for Arduiuo NodeMCU ESP8266 ESP32 Modbus RTUProduct Name:Packing list:RT48D02_RT59E02_RT6AF02_RT39D01 2.4G TTL/RS485/RS232/USB Wireless Transceiver Module（Please select the version you need）Overview: RT48D02_RT59E02_RT6AF02_RT39D01 is a TTL/RS485/RS232/TYPE-C 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 commandWhen 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 settingsPerformance Parameter: Working voltage: DC 5V-15V;Frequency range: 2400~2525MHzTransmission power: 11dBm;Receiver sensitivity: -84dBm@1MHz;Working temperature: -40~+85℃;Baud rate: 1200, 2400, 4800, 9600 (Default), 19200, 38400, 57600, 115200Open-field transmission distance with sufficient power supply: 80-100 metersSize: 34 x 15 x 3mmWeight:2.5gPinout :1 VCC: DC 5V~15V positive power supply;2 GND: power ground3 A+: 485 data line4 B-: 485 data line5 CMD: AT mode switch port6 RES: Factory reset portNote: After the two ports of RES are shorted for 5 seconds, the module will restore the factory settings and restart automatically.Power supply description:The transmit current is 50mA (+11dBm); the receive current is 25mA, please use a small ripple power supplyNote: 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''RT48D02 RT59E02 RT6AF02 RT39D01 AT command detailed description''Wiringdiagram:Application example: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.Please use DC 7-12V power supply, if only 5V power supply, please reduce the transmitting power(AT+POWER=4)
