|The ODROID-C2 is a 64-bit quad-core single board computer(SBC) that is one of the most cost-effective 64bit development boards available in the ARM world. It can function as a home theater set-top box, a general purpose computer for web browsing, gaming and socializing, a compact tool for college or office work, a prototyping device for hardware tinkering, a controller for home automation, a workstation for software development, and much more.
Some of the modern operating systems that run on the ODROID-C2 are Ubuntu, Android, ARCHLinux, Debian, with thousands of free open-source software packages available. The ODROID-C2 is an ARM device -- the most advanced architecture for mobile devices and embedded 64-bit computing. The ARM processor’s small size, reduced complexity and low power consumption makes it very suitable for miniaturized devices such as wearables and embedded controllers.

* An additional MicroSD card or an eMMC module is required to install the OS.
We recommend the eMMC module as it has much higher performance than standard MicroSD cards.
* Remove the Jumper on J1, if you don't use the USB OTG port as a power input.
It will reduce the power consumption and heat significantly.
* ARM 64bit is a very new platform and some system specific Linux softwares are not working stably at this moment.
So there might be the compatibility issues frequently and we may need longer time to fix the issues.
STORY ABOUT THE ODROID-C2
Here is the comparisons to give you better understanding of ODROID-C2.
ODROID-C2 vs ODROID-C1 vs Raspberry Pi2
Both are Linux-friendly ARM® single-board computers for various applications and purposes.
The ODROID-C2 has many advantages over the Raspberry Pi2.
The processor is an S905 1.5GHz Quad-core from Amlogic with 2GByte DDR3 RAM, Gigabit-Ethernet and IR-receiver. The size of this computer is still only 85 x 56 mm with a weight of 40g, and offers silent operation, 2~5W average power usage, and instant portability, since it fits in a shirt pocket.
One powerful feature of the ODROID-C2 is an SD 3.01 standard compatible UHS-1 MicroSD card, as well as the faster eMMC module, can be ordered with the ODROID-C2, and arrives with the popular Ubuntu operating system already installed. Insert the MicroSD card into the slot, connect a monitor, a keyboard, a mouse, Ethernet and power cable, and that’s all you need to do to use the ODROID-C2! Browse the web, play games, run office programs, edit photos, develop software, and watch videos right away.
The ODROID-C2 also has a 40+7pin GPIO header to make a physical interface between the board and the outside world. The 40+7pin interface headers include PWM, I2C, I2S, UART, ADC and GPIO function.
The IR receiver and ADC features on the ODROID-C2 offer many options for building great DIY projects.
CPU and RAM performance comparison
We ran several different benchmarks to measure the computing power on the ODROID-C2. The same tests were performed on the Raspberry Pi 2, ODROID-C1, ODROID-U3 and ODROID-XU4 for easier comparison.
The values of the test results were scaled uniformly for comparison purposes. The computing power of the C2 was measured to be ~2-3 times faster than the latest Raspberry Pi 2 thanks to the 1.5Ghz Cortex-A53 cores and much higher memory bandwidth. The high-performance 2GB DDR3 RAM is an additional advantage allowing most programs to run smoothly on the C2. The best performance that we can archive is the below.
Antutu Scores on Android5.1 Lollipop
ODROID-C2 shows around 33,700pts while ODROID-C1+ shows around 21,200pts. So you can run Android OS more smoothly. Note that the XU4 shows around 51,000pts thanks to the much faster A15 cores and Mali-T628 MP6 GPU cores. But the ODROID-C2 has higher rate of the “Performance per Dollar” probably.
Storage I/O comparison
The C2 can boot from a MicroSD card or an eMMC module. The MicroSD interface supports the higher performance UHS-1 mode as well. File access of a 512MB file (read/write) on two different storage options shows distinct performance differences. The eMMC 5.0 storage is ~7x faster than the MicroSD Class-10 card in read tests. The MicroSD UHS-1 card is ~2x faster than the MicroSD Class-10 card in read tests. The MicroSD UHS-1 card provides a great low-cost option for many applications!
To obtain the results in the storage I/O comparison graph, type the following lines at a command prompt.
Write speed command :
$ dd if=/dev/zero of=test.tmp oflag=direct bs=8M count=64
Read speed command :
$ dd if=test.tmp of=/dev/null iflag=direct bs=8M count=64
The 4K HDMI output shows gorgeous desktop screen on 3840 x 2160 UHD resolution.
But the rendering speed is not good due to the limited performance.
4K video playback on the Android OS is quite stable and fast for 4K/HEVC playback on a real 4K display.
