Advance with the RN171 TCP / IP module WiFi shields allow connection of Arduino / Seeeduin wireless networks up to 802.11b. The RN171 module supports TCP, UDP, FTP, and HTTP communication protocols to meet the needs of many wireless and Internet IoT (Internet of Things) network projects, such as smart home appliances, robot controllers and personal air stations.
Shields emit powerful signals with a large and new stable antenna card. You can choose which digital pins (D0 to D7) to use for the RX and TX with the arduino default communication protocol UART / Serial and the two jump lines we have included. The shield has two Grove connectors, I2C and Serial, and can be plugged with other Groves.
