![enter image description here][1] ![enter image description here][2] ![enter image description here][3] **DESCRIPTION** 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. **Features:** Various demos with step-by-step tutorials Low power consumption Compatible with Arduino, easy to get started with CMD Support **Specifications:** Voltage:3.3~5.5 V Current:25~400mA Transmit power:0-10 dBm Frequency:2402~2480 MHz Interface : UART (Software serial, you can choose the digital pins as RX and TX of RN171) Network rate:1-11 Mbps for 802.11b/6-54Mbps for 802.11g Secure WiFi authentication:WEP-128, WPA-PSK (TKIP), WPA2-PSK (AES) Built-in networking applications:DHCP client, DNS client, ARP, ICMP ping, FTP, TELNET, HTTP, UDP, TCP RN-171:WIFLY GSX 802.11 b/g Wireless LAN Module. **Documents** Please visit our [wiki][4] page for more info about this product.
