USB to I2C conversion should be easy, powerful, and fast! Convert USB to I2C using over a virtual COM port with two simple commands for writing and reading I2C data. Connect NCD I2C devices with a desktop computer using this tiny I2C adapter and take control using our software or pick apart the source code and write your own software in any language that supports the FTDI FT32XS virtual COM port driver (which is just about all computers and languages). Plug in our USB to I2C converter into any available USB port on your PC and it mounts as a COM port, start sending commands at 115.2K Baud. Use our FREE AnyI2C software and start talking to the complete ecosystem of NCD I2C Devices with just a few button clicks. Watch data communications in the Log window so you can see it work.
Use this USB interface to read sensors, control relays and PWM controllers. Use in industrial 4-20 mA read/write applications, and much more. Read light sensors, temperature/humidity sensors, potentiometers, moisture sensors, all at a very low cost. This converter is hardware compatible with all programming languages and operating systems that support the FT230XS. Drivers are available from FTDIChip.com.
Includes USB Type A to USB Micro Cable.

What is the NCD I2C Interface?
NCD is the creator of plug and play modular hardware using the NCD I2C Interface connector standard. NCD I2C devices allow you to chain together several devices on the I2C bus, and communicate to each device individually at high speed (subject to the limitations of I2C). The NCD I2C Interface uses a standard 4-Pin I2C Input and I2C Output connector. NCD I2C devices communicate 5V I2C data and provides 5V DC power through this connector. NCD I2C devices use standard I2C communications for all data transport, which is supported by nearly every microcontroller in production today. The NCD I2C Interface is strictly a 5V standard, which is ideal for transport across longer cables. NCD I2C devices always include a 6″ (152mm) 4-conductor I2C cable. NCD I2C Mini Modules always include a 3″ (76mm) 4-conductor I2C cable. Cables and connectors are available separately for designers who would like to include their own NCD I2C Interface into their designs.
Plug and Play Connectivity
NCD I2C devices will plug in to any available NCD I2C Output. This includes just about everything we make in the NCD IoT Category, including all NCD IoT devices. We also manufacture a wide range of I2C adapters that make it easy to plug NCD I2C Devices directly into most computing platforms. The NCD I2C Interface adapters are available for Arduino, Banana Pi, BeagleBone, Bluz, C.H.I.P., ESP8266, Onion Omega, Particle Photon and Electron, PyCom, Raspberry Pi, 2, 3, and Zero, and Windows. We are always working to add new platform support for NCD I2C devices. NCD I2C Interface devices are compatible with just about everything in the microcontroller industry.
Unlimited I2C Expansion
Based on our plug-and-play I2C interface standard, all NCD I2C devices are equipped with a I2C output port, making it easy to expand to a wide variety of sensors, current monitors, relay controllers, PWM controllers, and much more! We are always designing new expansions for our modular plug-and-play I2C framework. We are dedicated to building a product line of interconnected devices to simplify all forms of automation. Re-use or upgrade your hardware in seconds by selecting the modules that best fit your needs, and chaining them together using the included I2C expansion cables!
Powering NCD I2C Interface Devices
Some NCD I2C devices require a external power supply, others may be powered through the 4-Pin I2C bus connector at 5VDC, and other devices are jumper selectable between external and I2C bus power. All I2C mini modules are powered through the 5V I2C bus connector, greatly simplifying connectivity.
