Digi Connect ME Wired and Wireless Embedded Modules

 

The industry's first interchangeable secure wired and wireless embedded modules with plug-and-play functionality and comprehensive development tools for custom applications make it easy to add embedded web-enabled wired and wireless network connectivity.

The advances of personal computers and the proliferation of the Internet have laid the groundwork for an era in which billions of networked electronic devices will work invisibly and jointly with each other and with people. The introduction of wireless technology into the rapidly emerging world of ubiquitous networking creates a new dimension of network collaboration that complements existing wired infrastructures.

Making the right network technology decisions is a key factor for market success and defines the competitive edge of your products.

The Digi Connect ME family of secure embedded modules enables original equipment manufacturers to keep pace with ever-evolving networking technology by delivering complete and versatile embedded network connectivity solutions.

They are cost effective and easy to implement in existing and new product designs, while powerful enough to meet future product performance needs for a wide range of applications. These include retail systems, security/access control, medical devices, building/industrial automation, warehousing, and transportation systems.

Based on a common platform design approach, the Digi Connect ME and Digi Connect Wi-ME embedded modules offer seamless software and hardware migration. The family's form factor compatibility allows the "drop-in replacement" of a wired or wireless module in your product design.

In combination with the true long-term product availability and state-of-the-art wired and wireless security capabilities like SSL/TLS and WPA/WPA2, the Digi Connect ME family is the ideal choice to instantly network-enable your products.

Built on Digi's leading 32-bit NET+ARM processor technology, the Digi Connect ME family offers serial-to-Ethernet functionality through Digi’s plug-and-play firmware, and the freedom and flexibility of professional embedded software development provided by the easy-to-use, cost-effective and complete Digi JumpStart Kits™ for NET+OS® and Microsoft® .NET Micro Framework .
