Ruth's sister PL2303 1.8V USB TTL Module international power cord

SKU CH-2365-GTM2N

A PL2303 1.8V USB-to-TTL serial module for flashing and debugging at 1.8 volts

  • PL2303 chipset enables USB to TTL serial conversion
  • 8 V logic level suits low-voltage target boards
  • Compatible with Windows XP, 7, 8 and 10
  • Compact PCB module for firmware flashing and debugging

USB TTL Module for 1.8V Flashing

This PL2303 board converts a USB connection to a 1.8V serial TTL interface. It is designed for developers and hobbyists who need to flash or debug firmware on devices that operate at this specific low voltage. Driver support covers Windows XP, 7, 8 and 10.

Voltage Limit and Driver Scope

The module only works with targets that accept 1.8V logic levels; higher-voltage systems risk damage or communication failure. Official drivers stop at Windows 10, so newer operating systems may require manual configuration or may not be supported at all.

Questions about this item

Which PL2303 1.8V module version should I choose for flashing?

The board uses a PL2303 1.8V chip and provides a USB-to-TTL serial interface for flashing firmware on 1.8 V logic devices.

What does the 1.8V rating mean when the module is connected to a target board?

It means the TX, RX, RTS and CTS pins operate at 1.8 V logic levels, so the module can interface directly with 1.8 V microcontrollers or flash chips without level shifting.
