I/O Extender for TWN4 MultiTech Nano Development Board

The I/O extender is an optional expansion with additional interfaces for the TWN4 MultiTech Nano Development Board.

Both are designed to facilitate the development and testing of custom tailored apps for the versatile multi-technology dualfrequency RFID module TWN4 MultiTech Nano.

Thus pretty much any industrial scenario can be covered and the app can be tested before integrating the module into the client’s system.
