<p>将支持Wi-Fi(11b/g/n)和Bluetooth 4.1的Combo Chip，与ARM Cortex-M4(100MHz)内核的微控制器(MCU)封装在一起，凝聚为8.9x7.8mm尺寸的超小型模块。</p>

<p>MCU上不仅可以安装设备驱动器、WPA2等客户端，还能安装TCP/IP等协议栈、Bluetooth配置文件、应用软件，因此即使客户的设备上没有安装CPU，也能简单实现IoT设备。</p>

<p><strong>标准支持Cypress公司的WICED，并支持IoT所需的各种协议</strong></p>

<p>Cypress公司的WICED(Wireless Internet Connectivity for Embedded Devices)，是专为IoT设备提供快捷开发环境的解决方案。</p>

<p>WLAN功能支持STA/SoftAP模式、WPA2-PSK(AES)、WPS、Wi-Fi Direct等。Bluetooth支持Classic BR/EDR和BLE模式，并支持RFCOMM/SPP、A2DP、AVRCP、HF、HID配置文件。</p>

<p>不仅支持TCP/IP、HTTP等基本的网络协议，而且支持SSL/TLS等安全性协议、MQTT和Apple HomeKit等IoT专用协议。</p>
