USB to TTL Serial UART RS232 Adaptor (PL2303)

USB to TTL converters are an essential for prototyping – they provide a direct interface with the target device. This module connects to your computer USB port and there are 4 wires which connect with your target device.


  • Fully enclosed professional finish.
  • Built-in PL2303HX
  • Designed to be used for USB to TTL electronic projects
  • TTL interface output, easy to connect to your MCU
  • Dual 3.3V and 5V Power output (by Changing the red wire termination)
  • Can independently power the circuit with 5V or 3.3V
  • Compact design


  • Red – power. This pin provides up to 500mA current. YOU MUST NOT use other power supplies if you choose to power the target device with this Adaptor.
  • Black – ground (always needed, regardless if the Adaptor is powering the target device or not)
  • White RX (3.3V / 5V)
  • Green TX (3.3V / 5V)

3.3V and 5V Selection:

Open the plastic case (twist the USB connector and then evenly pull apart the plastic case) and change the red wire termination from the pad marked 5V or 3V3.
