MSC Technologies, a business group of Avnet Electronics, recently introduced the new WLAN-Module HDG820 for 802.11.b/g/n networks, designed by H&D Wireless AB (Sweden). The solution incorporates a complete IP protocol set running on an internal ARM Cortex core and is an ideal platform for advanced smart-home, IoT and M2M applications over Wi-Fi.
H&D Wireless AB specializes in world class Wi-Fi solutions, combining a deep knowledge of embedded wireless systems, silicon design and system software for cloud services and mobile phone apps. The company’s range of WLAN is deemed best in class in terms of size, power consumption in all modes, transmit/receive range, data transfer speed and cost. Wi-Fi solutions from H&D Wireless are supported on leading MCU platforms allowing easy access to the Internet as well as data and audio for consumer electronics.
The new HDG820 SiP-Module from H&D Wireless includes the Controller, WLAN transceiver and Memory and is delivered in an extremely small SMD package of 8 × 8 × 1.2 mm3. It can be controlled via UART / SPI which is also the interface for data transfer. With a power consumption of max. 220 mA and 250 µA in Sleep mode and an RF performance of +17 dBm in Tx and –96 dBm in Rx, it fulfills all requirements for typical building and home applications. An extended temperature of –40 to +85°C also makes it an ideal platform for Wi-Fi enabled sensors in industrial applications.
The HDG820 module is pre-certified for CE and FCC and of course Wi-Fi certified. In addition to its compact size only very few components need to be added to the BOM list (e.g., antenna and capacitors), allowing for extremely competitive new designs with all the benefits of WLAN solutions.
Even more interesting is the list of supported software features. Protocols like TCP/IP, HTTP and more as well as features like Soft-Access Point, Wi-Fi Direct and also security features like WPA are available and fully integrated. The Pico oWL API is designed to be compiled and executed on multiple processor platforms from 8 bit to 32bit and makes configuration really easy, also enabling full control of the module. H&D Wireless even supplies a Linux design environment.
Furthermore the Griffin Software, also delivered by H&D Wireless, supports full cloud computing capabilities and easy app integration with several reference designs available. All software is available for free. Development kits, demo applications and of course the modules itself are available at MSC Technologies in Europe and Avnet Electronics worldwide.
