Micro USB 5V 4-Channel Relay Module USB Control Relay Module Serial Port

Features 1.The module have MICRO USB and serial port , so they can communicate with PC and other device conveniently. 2.The normal working voltage for modules is 5V.And module of ICSE014A have a power interface of 5V. Parameters are as follows: ICSE012A ICSE013A ICSE014A Unit Remark CC 4 2 8 channel countof module I 400 250 700 mA working current U 5 5 5 V input voltage ? ? ? whether have serial port 9600 9600 9600 bit/s baud rate ofserialport F 1000 1000 1000 Hz Module control frequency × × ? Whether have power interface Interface: Modules all have Micro USB and serial port . Read following for details: 1.Micro USB: Standard micro USB mother mouth. 2.TX : Transmit 3.RX : Receive 4.5V : Volt current condenser 5.GND : Ground 6.Power Interface : Only ICSE014A have . Interface is used when Micro USB cannot give enough power. Usage method: USB usage method Module connect with PC through USB . The connection method is as follows: 1.Then open ”Relay Board Manager” to operate the module . Read ” RelayBoardManager_Reference” for details of the software. Serial port usage method Module can communicate with other device directly through serial port . Module can receive single byte from upper monitor ( baud rate 9600): Upper Monitor 0x50 0x51 ICSE012A 0xAB ICSE013A 0xAD ICSE014A 0xAC Module will turn to normal work state after receive “0x51” . Then every data byte will control the relay directly . Each bit controls a realy ( ‘0' mark start , ‘1' mark stop ) . Read following for details: Bit ICSE012A ICSE013A ICSE014A Remark 0 ? ? ?
