WiSmart EC19W is a family of ultra low power application ready versatile modules, which can fit into any existing or new electronic device to add Wi-Fi functionality and are fully certified. The EC19W is designed to be as small as possible including flash memory and antenna. In this way, the designer can integrate it into the smallest space possible and count on the module to do everything right out of the box.

It is based on an ultra-low power, Wi-Fi chip with support for Wi-Fi Direct, WPS, legacy Wi-Fi Client and SoftAP modes, full TCP/IP stack, HTTPS/SSL, cloud services integration and much more. It includes Flash memory, an antenna and wireless certifications.

For device configuration, Econais has developed ProbMe™, a proprietary configuration method which enables any Wi-Fi device to configure the EC19W module without the need of any application. It is also possible to configure multiple devices at once.

Plenty of 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.
