Elecbee FTDI USB-RS232-WE-1800-BT-0.0 Cable, USB to RS232 Serial, 1.8M, Wire END

Features:

USB to serial cable. RS232 is an interface form that supports serial communication protocol. It is D-type 9-pin, and RS485 and other interfaces are common. Since many computers no longer integrate serial ports, this cable is used to provide a connection method for serial devices.

USB-RS232-WE-1800

The USB connector contains a small circuit board featuring the FTDI FT232RQ

USB to TTL 5v 6 Pin UART serial cable is connected directly to a microcontroller UART or I/O pins

USB to UART cable with 5V TTL level UART signals. Wire ended output allows the most flexible connection

Introduction to RS-232

RS232 is a commonly used serial device, which is generally used to transmit data in the field of communication and human-computer interaction. Although the serial port system is more complicated than the parallel port system, it requires less data lines than the parallel port system during data transmission, so the efficiency is also higher. RS232 only needs 3 data transmission lines to complete data transmission. These three lines are used to "transmit data", "receive data" and signal ground wire...

In this connection, the "send" and "receive" lines are used to send and receive data between computers. As its name "serial port", data is transmitted serially. There are two pins TXD and RXD. There are other pins like RTS, CTS, DSR, DTR and RTS, RI. "1" and "0" are defined as two different voltage levels: 3V to 15V and -3V to -15V, respectively.
