USB-to-RS232 converter module with dust-proof cover for Arduino programming

  • PL2303TA chip enables USB to RS232 conversion for serial devices
  • Dust-proof cover protects the module contacts during storage and handling
  • Internal power cable supplies power directly from the host system
  • Designed for Arduino download cable use with straightforward connectivity

USB-to-RS232 converter with dust-proof cover

This module uses a PL2303TA chip to translate USB signals into RS232 levels for serial communication. It is intended for developers and hobbyists who need a reliable link between a modern computer and legacy or embedded hardware such as Arduino boards. The integrated dust-proof cover protects the connector when the adapter is not in use.

Sustained data transfer without driver reloads

The PL2303TA maintains a stable virtual COM port during long upload or debugging sessions, so the connection does not drop when the host system enters low-power states. It draws power directly from the USB bus, eliminating the need for an external supply during continuous operation. The adapter is not suited for applications that require galvanic isolation or voltage levels beyond standard RS232 specifications.

Questions about this item

How much power does the PL2303TA module draw when running continuously?

The module is powered directly from the USB port, so it draws only the small current the PL2303TA chip requires for USB-to-RS232 conversion.

What must my system provide for this adapter to work?

A standard USB-A port supplies both power and data; the RS232 side connects to the target device via its DB9 or header pins.
