WiFiBee-MT7681 (Support Arduino WiFi Wireless Programming)

The WiFi Bee MT7681 is an Arduino WiFi XBee module based on the MT7681 serial Wi-Fi module. It is compatible with an XBee slot, supports Arduino wireless programming, and is ideal for Internet of Things (IoT), home automation, and robotics applications.

The WiFi Bee supports the IEEE802.11b/g/n standard protocols, with 2.4G Wi-Fi bands, 14 channels, and WEP/WPA-PSK/WPA2-PSK/TKIP/AES encryption methods, compatible with many mainstream routers. It has STA and AP working modes, is free to switch, and supports TCP/IP communications. In addition, the WiFi Bee also supports SmartLink's intelligent connection. The unit is easy to use - just install the app (Android), and connect to your wireless router.

The WiFi Bee has the same pin mappings as an XBee. It can be inserted in any device which has an existing XBee socket for full networking capability. For Arduino UNO and Arduino Mega 2560 boards, the WiFi Bee can also be used as a wireless code upload module eliminating the need for a USB cable or physical connection. This is very convenient when debugging robots or mobile platforms. In addition, the module breakouts include three I/O ports. Use it as a Wi-Fi remote control - each I/O supports software PWM outputs. You can configure the parameters using serial AT commands via the serial terminal.
