Is ODROID can replace desktop

        The ODROID is a series of single-board computers and tablet computers created by Hardkernel Co., Ltd., an open-source hardware company located in South Korea. Even though the name ‘ODROID’ is a portmanteau of ‘open’ + ‘Android’ the hardware is not actually open because some parts of the design are retained by the company. Many ODROID systems are capable of running not only Android, but also regular  Linux distributions.

          Several models of ODROID's have been released by Hardkernel. The first generation was released in 2009, followed by higher specification models. Current boards are priced US$32 for the C1+, US$40 for the C2 and US$74 for the XU4.

         C models feature a Amlogic system on a chip (SoC), while XU models feature a ExynosSoC. Both include an ARM central processing unit (CPU) and an on chip graphics processing unit (GPU). 

         CPU architectures include ARMv7-A and ARMv8-A, a board memory range from 1 GB RAM to 2 GB RAM. Secure Digital SD cards are used to store the operating system and program memory in either the SDHC or MicroSDHC sizes. Most boards have between three and five mixed USB 2.0 or 3.0 slots,HDMI output, and a 3.5 mm jack.

         Lower level output is provided by a number of general-purpose input/output (GPIO) pins which support common protocols like I²C. Current models have an Gigabit Ethernet (8P8C) port and eMMC module socket.

ODROID-XU4

                  ODROID-XU4 is a new gwnwration of computing device with more powerful , more energy- efficient hardware and a smalller form factor.

               Offering open source support, the board can run various flavors of Linux, including the latest Ubuntu 16.04 and Android 4.4 KitKat, 5.0 Lollipop and 7.1 Nougat.

               By implementing the eMMC 5.0, USB 3.0 and Gigabit Ethernet interfaces, the ODROID-XU4 boasts amazing data transfer speeds, a feature that is increasingly required to support advanced processing power on ARM devices. 

              This allows users to truly experience an upgrade in computing, especially with faster booting, web browsing, networking, and 3D games.

ODROID -C2

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.
