ODROID | Hardkernel

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, ARCHLinux, Debian, and OpenELEC, 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.

* Amlogic ARM® Cortex®-A5(ARMv7) 1.5Ghz quad core CPUs
* Mali™-450 MP2 GPU (OpenGL ES 2.0/1.1 enabled for Linux and Android)
* 1Gbyte DDR3 SDRAM
* Gigabit Ethernet
* 40pin GPIOs + 7pin I2S
* eMMC4.5 HS200 Flash Storage slot / UHS-1 SDR50 MicroSD Card slot
* USB 2.0 Host x 4, USB OTG x 1 (power + data capable)
* Infrared(IR) Receiver
* Ubuntu or Android OS

The C1+ is the latest revision of the original C1.
It replaced the original C1 in July 2015. Compared to the C1 it has :

- Standard Type-A HDMI connector
- An included heat sink on board
- An I2S bus to support HiFi audio add-on boards
- CEC function that doesn't require the RTC backup battery
- A power path from USB OTG port as well as DC barrel connector
- Improved SD-card compatibility

Because of the above changes, the original cases and heat sinks are not compatible.

* 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.

Hardware Comparison

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, SysBench and N-Bench 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 RPi2 was clocked at 900Mhz using a Sandisk UHS-1 8GB SDCard running the Raspbian 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.

Benchmarks(Index Score)	ODROID-C1+	Raspberry Pi 2	Ratio
Dhrystone-2	1262.8	1006.6	1.25
Double-Precision Whetstone (x3)	1318.8	1076.1	1.23
Nbench2.2.3 Integer ( x40)	1208.0	840.0	1.44
Nbench2.2.3	1050.0	809.0	1.30
SysBench CPU ( 1/T * 50000)	863.6	669.3	1.29
SysBench RAM	998.3	574.7	1.74

The results show that the CPU computing benchmark is about 30% faster on the C1+ and RAM memory access speed is about 75% faster on the C1+.
Note that above benchmark scores were converted to make an easier comparison.

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:
Server agent on the C1+ and Client agent on the host PC
ruppi@ruppi-desktop:~$ iperf -s 192.168.2.10 -P 10
[SUM] 0.0-10.1 sec 1.10 GBytes 928 Mbits/sec

Server agent on the host PC and Client agent on the C1+
odroid@odroid:~# iperf -c 192.168.2.2 -P 10
[SUM] 0.0-10.0 sec 467 MBytes 392 Mbits/sec

Server agent on the RPi and Client agent on the host PC
ruppi@ruppi-desktop:~$ iperf -c 192.168.2.11 -P 10
[SUM] 0.0-10.3 sec 121 MBytes 98.6 Mbits/sec

Server agent on the host PC and Client agent on the RPi
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.
