Embedded module simplifies local networking

One of the most popular and simplest approaches to Web-enabling a product is to embed an Ethernet interface and connect it to a corporate LAN. Connect One took this approach to a new level with the Nano LANReach, an embedded-LAN module that easily connects any embedded device to 10/100BaseT LANs with minimal programming. Measuring only 2.5×3.5 cm, including a built-in RJ-45 connector, the Nano LANReach offers plug-and-play serial-to-LAN functions with a full suite of Internet protocols, applications, and security engines. Nano LANReach offers the latest Internet SSL (secure-sockets-layer) encryption algorithms. In addition, the module serves as an inherent firewall, protecting the embedded application from attacks originating from the Internet. The Nano LANReach uses the same pinout as the Nano WiReach Wi-Fi module, allowing one PCB (printed-circuit-board) design to support either LAN or Wi-Fi connectivity.

Because Connect One based Nano LANReach on the company’s iChip, customers can switch to a chip-based implementation embedded on their own PCBs. The approach typically reduces the LAN-interface cost to less than $10. The module operates at an industrial-temperature range of −40 to +85°C (−40 to −185°F) and complies with ROHS (restriction-of-hazardous-substances) directives. Prices for Nano LANReach start at $38. The $160 II-EVB-363ML evaluation board provides an environment for easily developing applications and testing the Nano LANReach.
