Ruth's sister FT232RL USB UART TTL Adapter 1.8v 3.3v internal power cable

SKU CH-PQ7W-VEQPT

USB-to-UART serial converter with 1.8 V and 3.3 V logic levels for Arduino and Android development

  • FT232RL chip provides reliable USB-to-serial conversion
  • 8 V and 3.3 V levels suit a wide range of logic families
  • Internal power cable simplifies connections inside a chassis
  • New condition ensures full manufacturer specification out of the box

FT232RL USB UART adapter for 1.8 V and 3.3 V logic

This USB-to-UART serial converter uses the FT232RL chip to bridge a computer and microcontroller projects. It supplies both 1.8 V and 3.3 V signal levels, making it suitable for Arduino boards, Android devices and similar development platforms. The adapter draws power directly from the USB port for simple connectivity.

Dual-voltage headroom for low-level serial work

The 1.8 V and 3.3 V outputs cover most modern logic families used in embedded development. It cannot drive 5 V logic directly, so designs requiring five-volt signalling will need an external level shifter. The single-channel UART handles standard asynchronous serial streams without hardware flow-control lines.

Questions about this item

Will the FT232RL adapter work with my older 1.8 V logic-level microcontroller?

Yes, the FT232RL adapter supports both 1.8 V and 3.3 V logic levels, so it can communicate directly with your older 1.8 V microcontroller without extra level-shifting hardware.

How can I confirm the FT232RL adapter is functioning correctly after connecting it?

Open a terminal program at the assigned COM port, short the TX and RX pins together, and verify that every character you type echoes back immediately.
