Samsung Exynos is largely known for its family of mobile processors, used as major components in popular mobile devices like the Galaxy S III, Galaxy Note II and Google Nexus 10. While this implementation of our chips is a major focus, we also work closely with partner companies to offer Exynos-based development platforms, or community boards. These platforms are designed to support development on Exynos-based mobile systems.

Community boards can help developers become familiar with the features and capabilities of Exynos processors, facilitating the development of new application software for different operating systems, such as Android and Linux. You may already be familiar with some of the most popular development platforms running on Exynos chips - the ODROID-U2, ODROID-X2 and Arndale Board.


Hardkernel's ODROID-U2 is a more recent, performance-upgraded version of the company's original ODROID-U board. This development platform is powered by an ARM® Cortex™-A9 Exynos 4 Quad Prime running at 1.7GHz, clocked slightly higher than in the Galaxy Note II. This ultra-compact, quad-core board is smaller than a credit card and significantly less expensive than other development boards on the market, costing just $89 USD on the Hardkernel site.

Key features include 2GB of low-power DDR RAM, a 440MHz Mali™-400 quad-core 3D graphics accelerator, two high-speed USB2.0 host ports, MAXIM audio codec with headphone jack and microphone on board, a microSD and MAXIM Power Management IC, as well as Android 4.x and Ubuntu 12.10 support. The ODROID-U2 also comes with numerous accessory options such as an eMMC module, Bluetooth module and IO expansion board.


The ODROID-X2 is similar to the ODROID-U2 in a number of ways but offers improvements on some key features. Running on a 1.7GHz Exynos 4 Quad Prime processor, the ODROID-X2 is an upgraded version of Hardkernel's well-known ODROID-X board. While more expensive and slightly larger than the ODROID-U2, the ODROID-X2 remains a powerful, low-cost dev board option at $135 USD.

Key features include 2GB of low-power DDR RAM, a 440MHz Mali™-400 3D graphics accelerator, six high-speed USB2.0 host ports, MAXIM audio codec and full-sized SD slot, as well as Android 4.x and Ubuntu BSP support. The ODROID-X2 also comes with numerous accessory options depending on developers' needs.

Arndale Board

InSignal's Arndale Board is the industry's first ARM® Cortex™-A15 dual-core development board, based on the 1.7GHz Exynos 5 Dual processor. The Arndale Board boasts some impressive features, including a Mali T-604 GPU for improved 3D graphics, WQXGA (2560x1600 at 60fps) display resolution support, USB3.0 and DDR3L RAM for higher data transfer speeds, among many other specifications. Featured at ARM® TechCon™ 2012 and other industry events, the Arndale Board represents a strong effort to support open source development of applications for use on Exynos-run mobile devices.

Using this community board, developers can produce superior mobile apps optimized for the ultra-fast Exynos 5 Dual processor and its enhanced 3D graphics capabilities. Arndale supports Android 4.1 Jelly Bean, allowing developers to tailor their applications for faster and smoother performance. The availability of this platform and the related source codes means that developers can expect a faster time-to-market for their software and hardware, which in turn benefits other users.
