EC19D incorporates the newest Wi-Fi 802.11b/g/n standards and features to give designers a full array of options for embedding the module in their designs. Features include: Wi-Fi Direct, ProbMe configuration, full TCP/IP stack, HTTPS/SSL, DHCP Client/Server, WPS, legacy Wi-Fi Client and SoftAP modes with WPA/WPA2 support, Serial to Wi-Fi, Cloud Service Support, and more. The modules measure 8 x 8 mm. ProbMe is a proprietary configuration method which enables any Wi-Fi device to configure the EC19D module without the need of any application. It is also possible to configure multiple devices at once. Ample flash memory is left free for any third party application that can make use of the well-defined API exported by the module. Serial to Wi-Fi is also available with a rich set of commands available in two formats: Human & Machine mode.
