This WiFi shield features the RN171 TCP/IP module to allow your Arduino/Seeeduino to connect with up to 802.11b/g wireless networks.

The shield's default communication protocol with the Arduino is UART/Serial, and you may select which digital pins (D0 to D7) to use for RX and TX with two jumper rows we've incorporated. The shield also has two on-board Grove connectors for I2C and Serial to allow the shield to be used with any of our Grove devices.

An on-board antenna allows the shield to cover a wider range and transmit stronger signals. The RN171 module supports TCP, UDP, FTP, and HTTP communication protocols to meet the needs of most wireless and Internet of Things (IoT) network projects e.g. smart home networks, robots control, personal weather stations.
