Comparison of WizFi250 (WiFi Module) Shield / Library in WIZnet and Seeeduino

WizFi250 Shield is one of Arduino WiFi shield. WizFi250 Shield is consist of WizFi250(WiFi Module) and interface board which has Arduino connector. There are 2 kind of WiFi shield by using WizFi250. (WizFi250-EVB and Fi250)

WizFi250

WizFi250 is an WiFi module for embedded system and provides UART and SPI interfaces which enable connections to any embedded design utilizing an 8/16/32-bit microcontroller via simple AT commands.
