Description
Wifi Shield (Fi250) V1.1 ------------------------ ![enter image description here][1] Wifi Shield (Fi250) V1.1 is a economic internet solution with Arduino. The Wi-Fi module support IEEE 802.11b/g/n mode, maximum speed up to 65Mbit/s. Wifi Shield (Fi250) V1.1 combine on board antenna; it’s easy to build you project in a small box. The module reserve a UFL connector, you can use an extra antenna to improve the signal range. There is a key on the board, just push one time to change wifi shield as AP mode. The module have a computer interface software, you can control and upgrade the module via USB-UART convertor. The wifi shield contain a Micro SD card socket, it’s like a recorder when wifi shield working as TCP, UDP server. Features: Module: WIZnet FI250 Operating Voltage: 5V or 3.3V (Auto select) Current: 300mA (maximum) Single band: 2.4GHz IEEE 802.11b/g/n Antenna: On board PCB antenna (reserver UFL connector) Memory: 1MB Flash Memory, 128KB SRAM, 1MB Serial Flash Interface: UART(default)/SPI(upgrade firmware) From:For more detail, please visit: http://www.seeedstudio.com/item_detail.html?p_id=2449 TCP Client Install Wifi Shield (Fi250) library, download demo code Wizfi250_Client. /* //This demo use Arduino Leonardo or Seeeduino Lite.
