The USB to RS232 TTL PL2303HX Cable Adapter Arduino is a converter module that allows RS232 TTL devices or development boards (DEMO BRD) to be connected to a computer via a standard USB port. This adapter is a practical and efficient solution for those working with Arduino and other electronic systems that require TTL serial communication.
Key features:
- Integrated chip: TTL COM PC-PL2303HX, which enables automatic conversion between USB and RS232 TTL.
- Connectors: Standard USB type A male and 4-pin TTL connector for easy integration.
- Cable length: 1000 mm (39 3/8 inches), providing flexibility in connection.
- Operating system compatibility: Compatible with Linux, Mac OS, WinCE, Windows XP, 2003, Vista and Windows 7. Not compatible with Windows 8 or Windows 10.
- Cable colours and functions:
- Black: GND (ground)
- Green: TXD (data transmission)
- White: RXD (data reception)
- Red: VCC (5V power supply)
- Connection mode: Uses three main lines (RX, TX, GND) and VCC power for a simple and secure connection.
- Important note: To avoid damage, adjust the jumper to select the 3.3V or 5.0V output according to the power required by the microcontroller before connecting to the computer.
Typical uses:
- Development and testing with Arduino boards and other microcontrollers.
- Connecting RS232 TTL devices to modern computers without a serial port.
- Electronics projects that require USB to TTL serial communication.
Compatibility and support: This adapter supports Linux, Mac OS, WinCE and Windows (XP, 2003, Vista and 7). It does not work with Windows 8 or Windows 10, so it is recommended to check the operating system before purchase. PL2303 drivers for Windows are available for download from official websites.

Customer Questions & Answers
What advantages does the PL2303HX adapter offer over other USB to TTL converter chips such as the CH340 or FT232RL?
The PL2303HX stands out for its broad compatibility with older operating systems (Windows XP, Vista, 7, Linux and Mac) and ease of use on development boards. However, the FT232RL chip usually has better support for newer systems and driver updates, while the CH340 is cheaper but can sometimes be less stable during prolonged transmissions. The PL2303HX is a good choice for projects where compatibility with older systems is key.
What are the dimensions, weight and exact contents included in the box of this USB to RS232/TTL adapter?
The adapter includes a cable approximately 1000 mm long, with a USB Type-A male connector and a 4-pin TTL connector. The weight is typically under 50 g. The package contains only the PL2303HX adapter cable, with no additional accessories.
What procedure is recommended for correctly connecting and installing the adapter with a 3.3 V or 5 V microcontroller?
To connect the adapter to a microcontroller, make sure the jumper is set according to whether you are using 3.3 V or 5 V, and only make the connection when the adapter is NOT connected to the computer (to avoid current damage). The GND, TXD and RXD pins are commonly used for serial communication. Always check that the logic levels match before connecting.
What common problems can arise when using this type of adapter cable, and how can they be solved?
Common issues include driver incompatibility on newer Windows versions, COM port detection errors and TX/RX signal crossing. To fix this, use it on supported systems, download the specific PL2303HX driver, and check the signal connections are correct (TX to RX and RX to TX). Failure to detect on newer Windows versions usually has no guaranteed fix.
Which operating systems is this adapter compatible with?
It is compatible with Linux, Mac OS, WinCE, and Windows XP, 2003, Vista and 7. It is not compatible with Windows 8 or Windows 10.
Can I use this adapter with Windows 10?
No, this adapter does not work with Windows 8 or Windows 10 due to incompatibilities with PL2303 drivers.
What is the length of the adapter cable?
The cable is 1000 mm (39 3/8 inches) long, providing enough flexibility for convenient connections.
What pins does the TTL connector include?
It includes four pins: GND (black), TXD (green), RXD (white) and VCC 5V (red).
Do I need to configure anything before using the adapter?
Yes, you must adjust the jumper to select the correct voltage output (3.3V or 5.0V) to avoid damage to the connected device.
