Which I2C Bus Host Adapter is right for me?
MCC offers a wide selection of I2C Bus Host Adapters. All these adapters interface a host computer or single-board computer to an I2C Bus, but offer different capabilities, hardware, features, application program interfaces (MS.NET Class, LabVIEW VIs, ASCII-Text, or Windows DLL), and host computer interfaces (USB, Ethernet, or RS-232).
This FAQ will help you decide which adapter is right for you, including free software, custom programming considerations, and our application recommendations. If you have industrial grade test requirements, our I2C Systems, Boards, Modules, and Cables may be just the solution you need.
If you need more help, send your questions to us at support@mcc-us.com.
