A Touchscreen That Also Reads the Machine The GEVINO TFT puts a local operator interface and programmable I/O on the same board. A button can change an output, a sensor can update a gauge, and an optional W5500 module can connect that application to Ethernet. The useful distinction is where each job runs: the SAMD21 executes the control program, the RA8876 handles the display, and the W5500 provides the wired network interface. GEVA Elettronica designs and manufactures the GEVINO family in Almese, near Torino, Italy. Its TFT models combine Arduino Zero compatibility with removable terminal…
