The ODROID-C1+ is esteemed to be the most powerful low-cost single board computer available, as well as being an extremely versatile device. Featuring a quad-core Amlogic processor, advanced Mali GPU, and Gigabit Ethernet, 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-C1+ are Ubuntu, Android, Fedora, Arch Linux, Debian, and LibreELEC, with thousands of free open-source software packages available. The ODROID-C1+ is an ARM device — the most widely used architecture for mobile devices and embedded 32-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.

* USB 2.0 Host x 4, USB OTG x 1 (power + data capable)
* Infrared(IR) Receiver
* Ubuntu or Android OS
* We guarantee the production of C1+ to the early of 2021, but expect to continue production long after.
Because of the above changes, the original cases and heat sinks are not compatible.
OS Image files and BSP source code are available in our WiKi : https://wiki.odroid.com/odroid-c1/odroid-c1

* 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 J8, if you don’t use the USB OTG port as a power input.
It will reduce the power consumption and heat significantly.

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 1.5Ghz quad core processor is outperforming Broadcom BCM2835.
We launched the ODROID-C1 in December 2014 and RPi2 was released in February 2015.
The ODROID-C1 was superseded by the ODROID-C1+ in August 2015.
Here is the comparisons to give you better understanding of ODROID-C1.
ODROID-C1+ vs Raspberry Pi2
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

We ran a simple, popular benchmark called UnixBench, NBench and mbw100 to compare the performance of the popular 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.
|Benchmarks (Index Score)||Raspberry Pi 3||ODROID-C1+||ODROID-C2||ODROID-XU4|

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
|Media access performance||RPi2 Model B||ODROID-C1+|
|eMMC Read (MB/s)||NA||62.2|
|eMMC Write (MB/s)||NA||25.1|
|MicroSD UHS-1 Read (MB/s)||19.2||32.5|
|MicroSD UHS-1 Write (MB/s)||13.1||14.2|
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.
Ethernet IO comparison
To replicate the results in the Ethernet comparison graph, type the following lines at a command prompt:

pi@raspberrypi:~$ iperf -s 192.168.2.2 -P 10
[SUM] 0.0-10.3 sec 81.6 MBytes 66.6 Mbits/sec
Thanks to the Gigabit Ethernet available on the ODROID-C1+, the network performance of C1+ is an impressive six to nine times faster than Raspberry Pi.
As one can see from the testing results, the quad-core 1.5GHz ODROID-C1 can easily outperform the Raspberry Pi 2 board. Many test results show about 140% 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.
