This USB serial cable supplies +5V at up to 500mA (USB specification limit) along with TxD and RxD sginals -- no hardware handshaking. Now you can test the serial Data with this so cheap one to replace this FT232RL one(USBSerial Adapter). It is very easy to use, you just need to plug it into the computer there will be a com found in the computer. Then you Open the serial tester to test the Serial Data. Please Notice that if you need to program the Arduino board, this module can work, you need to purchase this USBSerial Adapter.
Note: The USB to serial port chip PL2303HX does not support Win 10.

Jargon buster
Plain-language definitions for the technical terms used above.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- RX
- RX means receive, usually showing data being received by the board. An RX indicator LED can help with troubleshooting USB or serial communication.
- TTL serial
- A simple serial data connection that uses microcontroller logic-level voltages (typically 3.3 V or 5 V) rather than the higher, inverted voltages of computer RS-232. When a device lists TTL serial, it can usually wire straight to a microcontroller's UART pins or to a USB-to-TTL serial adapter, but it needs a level converter before connecting to a true RS-232 port.
- TX
- TX means transmit, usually showing data being sent from the board. A TX indicator LED can help you see when the board is communicating or uploading code.
