Zentri Legacy Wi-Fi Modules

Zentri Wi-Fi modules offer an embedded TCP/IP networking stack and web server with RESTful API/websockets and SSL/TLS/HTTPS security and RF pads, allowing maximum antenna flexibility, and full regulatory certification. The modules ship with a fully licensed version of ZentriOS, the connectivity operating system of choice for resource constrained IoT devices that may require device management services. ZentriOS accelerates time-to-market by providing a common software foundation across multiple product lines. The OS provides integrated security, sophisticated network connectivity features, file management, rich peripheral interfaces and more.
