Latest version of prototyping board for IoT projects and applications

RS Components now offers availability of the latest version of the Arduino Yún Linux-based board, delivering advanced network connections for IoT projects. Providing excellent value and reliability, the board is aimed at design engineers, hobbyists and those in educational establishments. This IoT board is particularly suitable for education, as the platform, including hardware, software and documentation, is open source and freely available to all. The board allows easy connection to Wi-Fi or a wired network via the Yún Web Panel, plus a dedicated sketch called YunFirstConfig. The web panel allows easy management of preferences and the uploading of the sketch. The board also uses the Bridge Library, which hugely extends its capabilities based on the power of its Linux processor. A key characteristic of the board is its dual-processor offering, which includes an AVR Arduino ATmega32U4 microcontroller running at 16MHz, and the MIPS 24K based Atheros 9331 processor, running at 400MHz. Interfacing to 64MB DDR2 RAM and 16MB of Flash memory, this second processor runs both Linux and the OpenWRT wireless software stack, which enables connection to Wi-Fi and 10/100-Mbit/s Ethernet networks. Also, the board makes it possible to call programs or custom scripts on the Linux system via the Arduino to connect with Internet services. Compared to the original design, the Yún rev. 2 provides an improved and more robust power supply, as well as a new Ethernet connector and a horizontally mounted USB connector to save vertical space. The OpenWRT software stack has also been updated to the newest version, including all patches. The board also comprises a series of onboard signalling LEDs, which show connection to Wi-Fi or Ethernet networks, along with confirmation of power-on, system activity or connection to a USB key.
