WiFiBee-MT7681 (Support Arduino WiFi Wireless Programming)

The WiFiBee MT7681 is an XBee-compatible Wi-Fi module based on the MediaTek MT7681 chip. It plugs into any standard XBee socket to add Wi-Fi networking to your project, and supports wireless Arduino programming — upload sketches over Wi-Fi without a USB cable.

Supporting IEEE 802.11b/g/n with WEP/WPA/WPA2 encryption, the module operates in both STA (station) and AP (access point) modes. It communicates via UART serial and can be configured using AT commands. Three breakout I/O ports with software PWM support make it useful as a Wi-Fi remote control as well.
