Adafruit Interface Modules
An interface module is a computer hardware device used to facilitate communication between different devices. They come in various form factors of various sizes and are usually used to connect systems that use different protocols and data formats. Interface modules can be used in industrial automation and other industries to enable different communication methods. Interface modules are designed to connect two different types of systems that may use different protocols, different data formats, or different physical connections. Some of the most common types of interface modules are Ethernet modules, serial interface modules, and USB interface modules.
