FTDI FT201X USB to I2C Breakout Module, Female Pin Connection

The FTDI FT201X USB to I2C Breakout Module provides a USB to I2C slave interface with a regulated 3.3V power output rated up to 50mA.

Overview

This breakout module bridges a USB host and an I2C slave device without requiring a standard USB cable. The module plugs directly into the USB host connector, with the PCB pads making direct electrical contact. It also provides four additional control bus lines for enhanced functionality.

Power and Voltage Levels

The module includes a regulated 3.3V power output with a 50mA current limit, suitable for powering low-power peripheral devices. A fused 5V line is also provided for added circuit protection. The module operates internally at +3.3V logic levels, and all I/O pins are 5V tolerant, which allows safe use in mixed-voltage environments and helps prevent damage when interfacing with 5V logic devices.

Key Features

• USB to I2C slave interface
• Four general-purpose control bus lines
• Regulated 3.3V power output (50mA current limit)
• Fused 5V power line
• 5V tolerant I/O pins operating at 3.3V
• Direct USB host connection via PCB edge connector, no cable required
• Female pin headers for connection to target hardware

Applications

The compact form factor makes the module suitable for prototyping, development, and embedded system applications where space is limited. It can be used for debugging and communicating with I2C-based sensors, EEPROMs, and other integrated circuits. It is intended for electronics engineers, hobbyists, and developers.
