Arduino Ethernet with PoE module
The Arduino Ethernet is a compact development board with the Wiznet W5100 Ethernet interface built directly onto the board — no separate shield required. Based on the ATmega328 microcontroller, it features 14 digital I/O pins, 6 analogue inputs, a 16 MHz crystal oscillator, RJ-45 connection, power jack, ICSP header, and a reset button.
This version includes a Power over Ethernet (PoE) ready magnetic jack. Because the Ethernet interface is integrated, there's no USB-serial driver on-board — you'll need an FTDI breakout or USB-serial adapter to upload sketches. An on-board micro-SD card slot allows you to store and serve files over the network.
Key Features
- ATmega328 Microcontroller – 32 KB flash (0.5 KB bootloader), 2 KB SRAM, 1 KB EEPROM at 16 MHz
- Wiznet W5100 Ethernet Controller – Built-in TCP/IP stack for wired internet connectivity
- PoE-Ready Magnetic Jack – Standard RJ-45 with Power over Ethernet support
- Micro-SD Card Slot – With active voltage translators (SS on Pin 4)
- 14 Digital I/O Pins – Pins 10–13 reserved for SPI/Ethernet, Pin 4 for SD card, Pin 2 for W5100 interrupt (when bridged)
- 6 Analogue Inputs – For sensor readings and analogue data
- Operating Voltage – 5V; input 7–12V recommended (6–20V limits)
- Current per I/O Pin – 40 mA; 3.3V pin supplies up to 50 mA
Ideal For
- Compact IoT projects where a separate Ethernet shield won't fit
- PoE-powered installations with a single cable for data and power
- Embedded web servers and network-connected data loggers
- Headless network devices and remote monitoring systems
Note: This board does not include USB-serial. An FTDI breakout or compatible USB-to-serial adapter is required to upload sketches. The board can be powered via the barrel jack (7–12V), PoE, or an FTDI cable.
