FTDI USB 2.0 UART adapter

This FTDI USB 2.0 to UART TTL module provides four selectable voltage levels of 1.8, 2.5, 3.3 and 5 volts through a 14-pin connector. It acts as a serial converter for direct communication with microcontrollers and embedded boards. The device connects via a standard USB 2.0 interface and is supported on Windows, Linux and Vista systems.

Replaces basic logic-level converters

The adapter replaces separate level-shifting circuits or fixed-voltage USB-to-serial cables when a project requires multiple logic voltages. The jump is worth it for developers who need one tool that covers 1.8, 2.5, 3.3 and 5 volt targets without swapping hardware. It is not for users who only need a single fixed voltage or who require isolation between host and target.

Questions about this item

What devices can the 14PIN connector on this module connect to?

The 14PIN connector provides the interface for the four selectable voltage levels of 1.8V, 2.5V, 3.3V and 5V, allowing connection to target boards that require one of those logic levels.

How is the voltage level selected during installation, and what mistake should be avoided?

Install the supplied jumper on the header corresponding to the required logic level — 1.8V, 2.5V, 3.3V or 5V — and ensure only one jumper is fitted; placing jumpers on multiple headers at once can damage the connected device.
