This small device gives you the opportunity to add internet connectivity to your existing design or machine. It comes packed in a compact plastic enclosure with DB25 male connector for the microcontroller ports. The PoE (Power-over-Ethernet) feature allows it to take power via the Ethernet cable with no need for external power supply adapter.

The TCP/IP stack provided by Microchip is royalty-free and allows you to do http, ftp, e-mail services, etc. You can control the PIC GPIOs using a web interface, and can aquire and send data from external sensors to other internet applications and clients. With 128kB Flash memory for programs and 128kB Flash memory for web storage, this device has all the resources usually needed for general embedded internet applications and interfaces of sensors and machines to the internet.

Note: This device does not have an external power supply connector. Your Ethernet switch/hub must support Power-over-Ethernet, otherwise you have to wire up your own power supply via the DB25 connector's Vin and GND pins (see schematics).
