Description

Brand Name: SZFYDOSH; Condition: New; Type: Expansion Board; Application: Product development , learning;

Ethernet W5100 network expansion module, can become a simple Web server or a network control to read and write digital and analog interface and other network applications. IDE can be used directly in the Ethernet library files can be achieved with a simple Web server.

Meanwhile, the version supports mini SD card (TF card) reader

The expansion board uses a stackable design, it can be directly plugged into the , while our other expansion boards can also plug in to.

Code:

/ *
* Web Server

* A simple web server that shows the value of the analog input pins.
