ODROID-XU4 development board powered by Samsung Exynos 5422 octa-core processor launched in summer 2015, but even after two years, it’s one of the fastest, if not the fastest, low cost development board on the market. It is also equipped with Gigabit Ethernet and USB 3.0 ports, but so far at $74, it was quite much expensive than slower peers. Hardkernel has now decided to lower the price to $59 plus shipping, which is really a good deal in terms of price/performance, and you’ll also benefit from close to two years development, as the board now supports Linux 4.9 with updates promised until early 2019.
Here’s a reminder of the technical specifications:
- SoC – Samsung Exynos 5422 quad core ARM Cortex-A15 @ 2.0GHz + quad core ARM Cortex-A7 @ 1.4GHz with Mali-T628 MP6 GPU supporting OpenGL ES 3.0 / 2.0 / 1.1 and OpenCL 1.1 Full profile
- System Memory – 2GB LPDDR3 RAM PoP (750 MHz, 12GB/s memory bandwidth, 2x32bit bus)
- Storage – Micro SD slot (up to 64GB) + eMMC 5.0 module socket (16, 32, and 64GB modules available)
- Video Output – HDMI 1.4a port up to 1080p
- Audio Output – HDMI, optional S/PDIF out via USB module
- Network Connectivity – Gigabit Ethernet, and optional USB Wi-Fi dongle with antenna
- USB – 2x USB 3.0 host port, 1x USB 2.0 ports
- Expansion – 30-pin header for access to GPIO, IRQ, SPI and ADC signals + 12-pin headers for GPIOs, I2S, and I2C
- Debugging – Serial console header
- Misc – Power and RGB LEDs, cooling fan header, power button, RTC
- Power Supply – 5V/4A power adapter (recommended) using 5.5/2.1mm barrel.
- Dimensions – 82 x 58 x 22 mm
- Weight – 60 grams with fan; 38 grams without cooler
One reason why the price is cheaper, is that the 5V/4A power adapter is not included by default, and if you don’t have your own, it will add $5.50.You’ll also find a list of accessories such as eMMC modules, enclosure, Cloudshell NAS kit, expansion boards, displays, etc… on the product page linked in the introduction.
The board can run various official or community-developed operating systems such as Ubuntu 16.04 + OpenGL ES + OpenCL, Android 4.4 to Android 7.0, Debian Jessie, Kali Linux 2.0, Arch Linux ARM, etc… and it is also supported by the Yocto Project. You’ll find the images and documentation on the Wiki, the source code is available on Github, and support in the active odroid forums and/or #odroid IRC channel.
