DFrduino FIO (Arduino Compatible)

The DFRduino Funnel I/O (Fio) is a board based on the original design of Arduino FIO. It is 100% compatible with original Arduino FIO.

Funnel is a toolkit to sketch your idea physically, and consists of software libraries and hardware. By using Funnel, the user can interface to sensors and/or actuators with various programming languages such as ActionScript 3, Processing, and Ruby.

Arduino Fio is compatible with Funnel. It has connections for a Lithium Polymer battery and includes a charge circuit over USB. An XBee socket is available on the bottom of the board. The Fio has been designed to be wirelessly reprogrammable.

  • ATmega328V running at 8MHz

Odroid XU

The ODROID-XU is based on Samsung Exynos5 Octa processor
Exynos-5410 which has ARM’s big.LITTLE architecture with Cortex-A15 Quad + Cortex-A7 Quad and Samsung’s LPDDR3 2GB.

Every developer wants to know the performance of new platform. The Samsung Exynos5 Octa SoC is mighty competitive as shown by following initial benchmarks compared to a Calxeda quad-core Cortex-A9 SoC, the TI OMAP4460 dual-core A9 1.2GHz SoC, and an Intel Atom D525 1.8GHz dual-core CPU plus Hyper Threading.

The first tests were done with Ubuntu 13.04 Linaro(13.07) server version and Kernel 3.4.5 to feel the speed of ODROID-XU. We used the famous Phoronix test suit for benchmarking on Linux.
Let’s start the bench marking with NAS Parallel Benchmarks which were developed by NASA. The NAS Parallel Benchmarks (NPB) are a small set of programs designed to help evaluate the performance of parallel supercomputers. The benchmarks are derived from computational fluid dynamics (CFD) applications and consist of five kernels and three pseudo-applications in the original "pencil-and-paper" specification (NPB 1). The benchmark suite has been extended to include new benchmarks for unstructured adaptive mesh, parallel I/O, multi-zone applications, and computational grids.
