32-channel IO expander with 14 analog inputs. It helps in connecting devices to the computer via the Ethernet interface and is controlled by the built-in, easy-to-use network interface or any popular terminal emulator that supports the TELNET protocol. Each module is shipped with a unique MAC address. All outputs are available on screw terminals, which makes it easy to connect external devices. The module will be used in home automation projects, lighting systems and garden equipment. Full documentation is available on the product page.
