Featured with RN171 TCP/IP module, the WiFi shield allows your Arduino/Seeeduino to connect wireless networks up to 802.11b/g. The RN171 module supports TCP, UDP, FTP and HTTP communication protocols, which meet the needs of most wireless and Internet of Things (IoT) network projects, such as smart home networks, robots controls and personal weather stations.
The shield covers a wide range and transmit strong signals with the newly, stable on-board antenna. The default communication protocol with the Arduino is UART/Serial, and you can select which digital pins (D0 to D7) to use for RX and TX with the two jumper rows we've incorporated. The shield also has two Grove connectors of I2C and Serial to make it can be plugged with any other Groves.
The shield is well documented with demos and you can check the User Manual here online.
