W5500 ETHERNET DEVELOPMENT BOARD (WITHOUT POE)
Description
Keyestudio W5500 is based on the microcontroller of Arduino Ethernet.We have integrated USB download, TF card slot and more functions on it, fully compatible with UNO pins. You can quickly make your controller access to internet to build your network application.
Onboard comes with W5500 network module,which can make Arduino as simple Web server or read Arduino digital and analog interface application via network control. It can achieve a simple Web server through using Ethernet libraries in IDE, meanwhile, support MicroSD card (TF card) read and write, really with powerful functions.
