ODROID-C1+ (Hardkernel) ARMv7/1.5GHz 4core,Mali-450 MP2 GPU,1Gbyte DDR3 SDRAM,eMMC4.5 HS200 Flash

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.

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.
