When comparing ODROID-C2 vs ASUS Tinker Board, the Slant community recommends ASUS Tinker Board for most people. In the question“What are the best single-board computers?” ASUS Tinker Board is ranked 11th while ODROID-C2 is ranked 20th. The most important reason people chose ASUS Tinker Board is:
The ASUS Tinker Board offers performance that outclasses other single-board computers in this price range. It can easily be used as a daily PC substitute and it can easily handle some tasks that competitors (like the Pi 3 for example) find difficult. Things like image editing, streaming Full HD videos, and even playing some simple browser-based games can easily be done on the Tinker Board.
Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Good support for Ubuntu
The C2 has pretty decent support for Ubuntu and it can be used with it for basic day-to-day operations such as browsing the web and editing documents with LibreOffice among others.
Pro Superior performance compared with other boards
Pro Built-in heatsink
The ODROID C2 has a built-in heatsink which covers the CPU and two of the RAM chips.
Pro Can fit inside Raspberry Pi cases
Since its shape and size closely mimic that of Pi 3, it can fit on most Raspberry Pi cases available.
Pro Will have mainline kernel support
Pro Relatively low power requirements
The board by itself needs about 0.5A to run, but it's advised to use a 2A power supply for when peripherals are attached.
Pro Great value for the price
The ASUS Tinker Board offers performance that outclasses other single-board computers in this price range. It can easily be used as a daily PC substitute and it can easily handle some tasks that competitors (like the Pi 3 for example) find difficult. Things like image editing, streaming Full HD videos, and even playing some simple browser-based games can easily be done on the Tinker Board.
Pro Fits on most Raspberry Pi cases
This single-board computer copies the form-factor of the raspberry pi to a T. The size is about the same and most of the connectors are at the same spots as the Raspberry Pi.
Pro The official OS is quite complete out of the box
You can get the official Linux image for the Tinker Board website. It's actually a customized version of Debian that's changed to work as smoothly as possible on Tinker Board's hardware.
It comes with all the essential applications every PC has nowadays (web browser, text, editor, etc.) and some more specialized tools that are used to control the GPIO pins and that allow more advanced users to "talk" to the hardware.
Pro Built-in WiFi and Bluetooth
This board has built-in WiFi and Bluetooth capabilities.
Pro Possible to connect an external WiFi antenna
Yes, you can add an external WiFi adapter to most SBCs but the ability to connect an external antenna to the embedded WiFi is a pretty rare feature.
Pro Unique and pleasant aesthetic
Unlike most boards on the market, the ASUS Tinker Board is rather aesthetically pleasing as well. It has an array of colours which help distinguish the different connectors. Especially nice are the GPIO pin headers which are all colour-coded to identify the various types of pins.
Pro Gigabit Ethernet on board
And since it has a dedicated controller which is not shared with USB it's very fast an the speed doesn't depend on USB usage (and vice versa).
Pro Previous Raspberry Pi owners will find themselves at ease with the GPIO library
The Tinker Board uses the same GPIO libraries as Raspberry Pi does. This means that users coming from Raspberry Pi who want to play around with the Tinker Board's GPIO pins will find it very easy to do so.
Cons
Con No built in WiFi
There is no built-in WiFi, and kernel headers for 3.14 are almost impossible to find, making driver compiling very difficult.
Con Old kernel available
Only the 3.14 branche is available
Con Early revisions use a 2.5mm power socket instead of a USB port
Early revisions of the C2 use a 2.5mm power socket instead of the micro USB port available on the board or any of the other USB ports. While not a drawback in terms of strength of the board, it's a bit annoying having to order a new power supply to work with the C2.
Later revisions of the board can use the USB port for charging. However, ODROID recommends using the power socket if there are several devices attached to the board because they can increase the draw up to 2A and a lot of cheaper USB power adapters won't do 2A.
Con Might have problems with default HDMI resolution when first starting up
It's not unusual for the C2 to have a "Mode not supported" message when first booted up and connected to a monitor through the HDMI port. This can be fixed by logging through SSH and editing the boot.ini on a FAT partition on the SD card to set the correct HDMI resolution and the process is detailed pretty well on the ODROID wiki but it may be out of scope for some users and pretty annoying for the rest.
Con The support behind it is lacking
The technical support provided by ASUS is rather lacking, compared to competitors and knowing how important ASUS is in the tech world. The documentation is lacklustre, the official website is filled with marketing-speak without any actual valuable information for someone who has already bought the board, and to top it off, the download link for the official OS is hidden away inside the ASUS website in the drivers section.
