FTDI FT201X USB to I2C Breakout Module, Female Pin Connection

The FTDI FT201X USB to I2C Breakout Module (UMFT201XB-01) is a compact and efficient interface board designed to bridge the gap between a USB host and an I2C slave device. Its unique design eliminates the need for a standard USB cable, as the module plugs directly into the USB host connector, with the PCB pads making direct electrical contact for a secure and reliable connection.

This breakout module provides a full USB to I2C interface along with four additional control bus lines for enhanced functionality. It features a regulated 3.3V power output, capable of supplying up to 50mA, which is ideal for powering low-power peripheral devices. A fused 5V line offers added protection for your circuits.

A key specification is its voltage level compatibility. While the module operates internally at +3.3V logic levels, all its I/O pins are 5V tolerant. This makes it exceptionally versatile and safe to use in mixed-voltage environments, preventing damage when interfacing with 5V logic devices.

The module's compact form factor, with a direct USB edge connector, makes it perfect for prototyping, development, and embedded system applications where space is at a premium. Its robust construction and direct connection method ensure a stable data transfer link for debugging and communicating with I2C-based sensors, EEPROMs, and other integrated circuits.
