FTDI USB-to-TTL Interface Module

The FTDI USB-to-TTL Interface Module is used to interface with Arduino or other microcontroller boards that do not have a built in USB interface.

This module is designed to be removed once the programming has be completed, allowing a smaller form factor for your project.  This board features a jumper header for selecting the operating voltage (3.3V or 5V) to work with 3.3V or 5V boards, 

We recommend using the FTDI USB-to-TTL Interface Module with the:

• Arduino Pro Mini (All models)
• Lilypad Arduino (ATMega328p Model)

The module comes with a mini-USB cable for connecting to your computer.  If you have USB-C connectors on your computer, grab our USB to USB-C Male Converter Adapter.

NOTE: This module has a jumper that selects the operating voltage (3.3V or 5V) for connecting to your board. Ensure you have the correct operating voltage selected, otherwise you may permanently damage your board.
