Arduino Ethernet Development Tools are microcontroller boards based on the Arduino Uno, and incorporating a WizNet W5100 TCP/IP Embedded Ethernet Controller. It can be programmed like an Uno via a six-pin FTDI -style serial connector. The Arduino USB-to-Serial adapter or any FTDI-style USB-to-serial connector can be used to program it. The A000060 includes an Arduino USB-to-Serial and allows a separate power-over-Ethernet (PoE) module to be soldered to the board to provide power from a conventional twisted pair Category 5 Ethernet cable. The A000061 includes an Arduino USB-to-Serial and a PoE module soldered to the board. A000068 allows a separate PoE module to be soldered to the board and the A000074 includes a PoE module to provide power. Arduino Ethernet Development Tools are IEEE802.3af compliant and work with all compliant PoE injectors currently available.
