FTDI FT200XD USB to I2C Breakout Module
Compact FTDI breakout module for USB to I2C conversion. Features 3.3V/5V tolerant I/O, direct plug-in design, and 8-pin connector.
The FTDI UMFT200XD-01 is a sophisticated USB-to-I2C breakout module built around the advanced FT200XD interface IC. This compact board facilitates seamless conversion from USB 2.0 full-speed to the I2C serial communication protocol, making it an essential tool for prototyping, development, and system integration where a direct USB connection is required.
A distinctive design feature is its direct plug-in mechanism. Unlike typical modules, it does not incorporate a standard USB connector. Instead, the board is designed to plug directly into a USB host port, where the PCB pads establish direct electrical contact with the port's internal pins. This streamlined approach reduces bulk and can enhance signal integrity.
Core Functionality and Specifications
- The I2C interface operates natively at +3.3V logic levels, ensuring compatibility with a wide range of modern microcontrollers and sensors.
- Crucially, all I/O lines are 5V tolerant, providing robust protection and flexibility when interfacing with legacy or mixed-voltage systems.
- The module provides four dedicated control bus lines for comprehensive I2C communication management.
- Onboard power regulation offers a 3.3V output, current-limited to a safe 50mA, and a 5V rail, both protected by a safety fuse to prevent damage from short circuits.
- All I2C signals are conveniently accessible via an 8-pin female connector, allowing for easy hook-up to breadboards, cables, or custom circuits.
Measuring just 43mm x 33mm x 15mm and weighing a mere 6.35 grams, this module is an incredibly compact and lightweight solution for adding USB connectivity to I2C-based projects. Its robust construction and FTDI's proven chipset ensure reliable data transfer and stable operation, making it an indispensable component for electronics engineers, hobbyists, and embedded system developers.
