Mini Nano W5100 Ethernet Network LAN Mini Nano Module Expansion Board

Feature This add on module allows you to connect the Arduino Nano to the Internet You can get all the benefits of using Arduino Nano It is fully assembled with the long pin head so you dont need to buy and solder the head separately You get the same stacking advantages as Arduino shields and you can run the same code It is based on the Wiznet W5100 Ethernet chip and is a network IP stack with both TCP and UDP functions Use the Ethernet library to write sketches that connect to the internet using additional modules The Ethernet Nano connects to the Arduino Nano using a concave long wire wrap head that extends through the board for board connection This will keep the pin layout unchanged and allow another add on module to be stacked on top or bottom The micro SD card slot can be used to store files for service over the network It is compatible with Arduino 0022 and later Ethernet libraries The sd card library is included in the standard Arduino distribution Arduino Nano uses SPI bus to communicate with W5100 and MicroSD card This is located on digital pins 11 12 and 13 on the Nano Pin 10 is used to select W5100 and pin 4 is used for MicroSD card These pins cannot be used for general purpose input output GPIO Please note that because the W5100 and MicroSD card share the SPI bus only one can be active at a time If you use two peripherals in your program at the same time they should be handled by the appropriate libraries However if you are not using a pe
