LORDWORLD PL2303 USB-UART Module V2 1.8V 2.5V 3.3V 5V

SKU CH-5WN4-W46VZ

USB-to-UART bridge with PL2303GS chip, jumper-selectable 1.8V, 2.5V, 3.3V or 5V logic levels and TXD, RXD, PWR LEDs

  • Broad Windows XP-to-11 driver support simplifies setup
  • PL2303GS chip delivers reliable USB-to-UART conversion
  • Three jumper-selectable VCCIO levels match 5 V, 3.3 V or target-board voltage
  • Open-jumper mode powers from 1.8 V to 5 V targets
  • On-board TXD, RXD and PWR LEDs show link status at a glance

USB-UART module for logic-level debugging

The LORDWORLD PL2303 module converts a USB-A port to a UART (TTL) interface for embedded development. It uses the PL2303GS chip and supports Windows XP through 11. Three onboard LEDs show TXD, RXD and power activity.

Jumper-selectable VCCIO replaces fixed-level

A three-position jumper sets the I/O voltage to 5 V, 3.3 V or leaves it open for target-powered operation at 1.8 V, 2.5 V, 3.3 V or 5 V. This removes the need for separate adapters when working with boards that run at different logic levels.

Suits makers debugging microcontrollers

Developers who switch between 5 V, 3.3 V and lower-voltage targets benefit from the single-module approach. Engineers needing galvanic isolation or higher baud-rate guarantees should look at a different solution.

Questions about this item

What logic-level voltages does the PL2303 module support?

The module handles 1.8 V, 2.5 V, 3.3 V and 5 V logic levels; set the VCCIO jumper to 5 V or 3.3 V for fixed output, or leave it open to draw power from the target board.

How do I install the driver on Windows 10 or 11?

Plug the USB-A connector into the PC, let Windows fetch the PL2303GS driver automatically, then verify the COM port appears in Device Manager before opening your terminal program.

What do the three LEDs tell me during operation?

PWR lights when the board is powered, TXD flashes when the module sends data, and RXD flashes when it receives data, giving a quick visual check of traffic direction.
