Important: Due to the shutdowns in the Federal Revenue, which have been ongoing since November 2023, we are temporarily suspending our exports to avoid potential issues such as delays and lost orders.

IMPORTANT: we ship all our items from Brazil via priority mail or express mail (EMS), and the customer is responsible for customs release and any import duties that may be due in the destination country.

Product Information

Highlights

• Wiznet W5500 ethernet chip, the evolution of W5100
• EEPROM memory with registered MAC address
• 32Kb buffer and up to 8 simultaneous connections
• Power down mode for energy saving
• Software library with the same interface as the standard Arduino Ethernet library

Description

The Ethernet Nanoshield allows to connect your project directly to the Internet. Some things you can do are:

• Browse websites and services on the Internet
• Communicate with other devices on your local network
• Run a simplified web server on your Arduino or Alevino
• Send local data to the Internet, such as sensor data
• Send e-mails

The Ethernet Nanoshield utilizes the W5500 chip from Wiznet, which is an Ethernet network controller and communicates with your project’s microcontroller over a SPI interface. This chip is a more modern version of the chip used by the official Arduino Ethernet Shield, featuring more memory (32Kb against 16Kb) and a greater number of simultaneous connections (8 against 4).

The programming is done using our Nanoshield_Ethernet library, which is compatible with the standard Ethernet library from Arduino, giving access to the same functions, besides a function for energy saving (power down mode).

A great advantage of the W5500 controller, in comparison to the other controllers available on the market, is that it has an internal TCP/IP protocol implementation (stack). This reduces significantly the tasks to be executed by the microcontroller, making the software faster and reducing the memory consumption. The 32Kbytes internal buffer allows one to store the sent and received data, while the microcontroller runs other tasks.

Another characteristic from the Ethernet Nanoshield is that it already comes with a MAC address on the EEPROM memory chip that is integrated to the board. This is a unique global address, which is registered exclusively for your board. This avoids address conflicts between your Ethernet Nanoshield and the other equipments on the network and you can also include it on a final product without having to buy MAC addresses from the registry entity.
