Quad Core Linux computer is now $35.00.
Don't put up with the slow single core computer anymore.
If you are considering a tiny computer for general purpose computing, software development or as a project platform,
the ODROID-C1 will give you a lot more satisfaction and fun with incredible performance for a very low price.
You can get more information from ODROID Magazine.
|OS Image files and BSP source code are available in our WiKi.|
Getting Started & Trouble shooting
* You need additional MicroSD card or an eMMC module to install the OS. We recommend the eMMC module for much higher performance boosting.
* ODROID-C1 power must be supplied via DC-Jack. Micro-USB port is only for data communication. So you need a proper power supply.
* U-boot/Kernel/Linux source code was released 15-Dec-2014. Android source code will be published in February after cleaning some license issues.

STORY ABOUT THE ODROID-C1
We had received tons of requests for the following model of ODROID-W. So, we started survey for components for ODROID-W2. Finding out the right CPU was the key of this project. Our original target was similar cost and similar performance as ODROID-W. But we realised that we cannot make ODROID-W2 once we reached to Amlogic S805 quad core processor. The performance of Amlogic S805 ARM® Cortex®-A5(ARMv7) 1.5Ghz quad core processor is outperforming Broadcom BCM2835 ARM11 700MHz.
Here is the comparisons to give you better understanding of ODROID-C1.
ODROID-C1 vs Raspberry Pi B+
Both are Linux-friendly, $35 ARM® single-board computers for various applications and purposes.
The ODROID-C1 has many advantages over the Raspberry Pi. The processor is an S805 1.5GHz Quad-core from Amlogic with 1GByte 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, 2~3W average power usage, and instant portability, since it fits in a shirt pocket.
One powerful feature of the ODROID-C1 is the row of GPIO (general purpose input/output) pins along the edge of the device. These pins are a physical interface between the board and the outside world. The 40pin interface header includes SPI, I2C, UART, ADC and GPIO function.
An SD 3.01 standard compatible UHS-1 Micro-SD card, as well as the faster eMMC module, can be ordered with the ODROID-C1, and arrives with the popular Ubuntu operating system already installed. Insert the SD 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-C1! Browse the web, play games, run office programs, edit photos, develop software, and watch videos right away.
The RTC, IR receiver and ADC features on the ODROID-C1 offer many options for building great DIY projects
Computing performance comparison
We ran a simple, popular benchmark called Unix-Bench (version 5.1.3) to compare the performance of the two boards. Tests were done using several manufacturer-provided images based on a clean install, and the “apt-get update && apt-get upgrade” commands were first run to ensure that both boards was up-to-date.
The RPi was clocked at 800Mhz using a Sandisk UHS-1 8GB SDCard running the Debian Wheezy OS. The C1 was clocked at 1.5Ghz using an 16GB eMMC with Ubuntu 14.04 OS. Both units were powered by a 5V/2A power supply and connected to the 1920x1080 HDMI output. Note that in order to utilize all four cores in the C1, the “./run –c 4” command was used.
|The results show that the Dhrystone-2 benchmark is about 8 times faster on the C1. File I/O benchmark is about 4 times faster because of the faster storage speed of the eMMC module. Overall performance test result show that the C1 is approximately 6 times faster than the RPi, even though the price of C1 is exactly same.|
Storage I/O comparison
To obtain the results in the storage I/O comparison graph, type the following lines at a command prompt. The first command tests the write speed, and the second command tests the read speed:
$ dd if=/dev/zero of=test.tmp oflag=direct bs=500K count=1024
$ dd if=test.tmp of=/dev/null iflag=direct bs=500K count=1024
If you use the eMMC storage, you can get about two to three times faster storage I/O read performance. However, an affordable microSD UHS-1 card can still achieve reasonably fast speeds thanks to the advanced SD 3.01 host controller in the S805 processor. The MicroSD card read performance on C1 is still about 1.7 times faster then RPi if you use the UHS-1 memory card.
As one can see from the testing results, the quad-core 1.5GHz ODROID-C1 can easily outperform the single-core 700MHz Raspberry Pi board, even when the Raspberry Pi is overclocked. Many test results show four to seven times more performance from the ODROID-C1 platform. Even though both platforms are Linux-friendly computing devices, the performance to cost ratio is much higher with the ODROID-C1. If you are considering a tiny computer for general purpose computing, software development, or as a project platform, the ODROID-C1 will give you a lot more satisfaction and fun with incredible performance for a very low price.
