With the core of W5500, the keyes W5500 network expansion board can be used as a simple Web server or control, read and write the digital and analog interfaces through the network. It is also compatible with keyes UNO R3 and keyes 2560 R3 development boards.
introduction
With the core of W5500, the keyes W5500 network expansion board can be used as a simple Web server or control, read and write the digital and analog interfaces through the network. It is also compatible with keyes UNO R3 and keyes 2560 R3 development boards.
When we upload the corresponding program to the control board, a simple web server is produced. Simultaneously, the shield supports mini SD card (TF card, the maximum support memory is 1G).
Moreover, it adopts a stackable design, therefore, a great deal of boards can be connected to it.
The 4 fixed holes with diameter in 3mm are apt to be mounted on other devices.
