Latest from U-blox, the ODIN-W262 is a new stand-alone multiradio module designed for Internet-of-Things applications. The professional-grade (-40C to +85C) module makes adding wireless connectivity to any product quick and easy, with the added benefit that it is radio type-approved in countries across the world. A robust, built-in antenna provides flexibility with respect to the module’s installed position and orientation. Applications include cable replacement running in Wireless Multidrop and Extended Data Mode for advanced multipoint operation with several radios operating simultaneously. The ODIN-W262, measuring only 14.8mm x 22.3mm x 4.5mm, needs no external host. It is ready-to-use and comes complete with embedded driver, stack and application for wireless data transfer. The module supports multiple concurrent Wi-Fi (2.4 GHz and 5 GHz), Classic Bluetooth and Bluetooth low energy (v4.0) links to provide the greatest flexibility possible, and it is easily configured using AT-commands. Future firmware upgrades will add micro access point, high-speed interfaces (such as RMII) and support for custom embedded applications. For example, the module will be able to act as a Wi-Fi access point or as a gateway between Wi-Fi and Bluetooth low energy sensors. These numerous configuration options minimize inventory requirements and reduce design effort and costs because one module can be software-configured for use in a variety of products. For example, a manufacturer may want to offer products in either Wi-Fi or Bluetooth versions, says the company. Herbert Blaser, Short Range Radio Centre head, U-blox, said: “Concurrent Wi-Fi and Bluetooth has many uses. In retail applications, Bluetooth low energy may be used to detect the closest printer while data is sent to that printer over Wi-Fi or Bluetooth classic. There are potential medical applications too. A patient monitoring device may be supervised via Wi-Fi at a central location in the hospital, while local communication with nurses is carried out over Bluetooth. For such medical applications, the module complies with the IEC 60601-1-2 standard.” The EVK-W262U is an evaluation kit for the module. It uses a single USB connection for data and power and comes complete with the u-blox configuration tool for Windows. For applications where an external antenna may be optimal, the company offers the ODIN-W260 module, which is a version with U.FL antenna connectors.
