Feature
●This is a multi-functional MCU board that combines the W5500 Ethernet module and the Uno board. We provide an English manual. Search "KEYESTUDIO KS0304" on Google to get an English manual and sample code
●We provide technical support services, if you have any questions, please feel free to contact us. For product details, please read the English manual before purchasing: wiki.keyestudio.com/Ks0304_Keyestudio_W5500_ETHERNET_DEVELOPMENT_BOARD_(WITHOUT_POE)
●Please note that MAC address is not unique. With the W5500 network module, you can turn your Arduino into a simple web server or read the Arduino digital and analog interface applications through network control
●It can accomplish a simple web server by using an Ethernet library in IDE, with a truly powerful function that supports Micro SD card (TF card) reading and writing
●Main Chip: ATMEGA328 Microcontroller, External Power Supply: 7-12V, (9V recommended), Digital Input and Output Pins: 14 (6 of which supports PWM)
