When comparing ODROID-W vs Banana Pi, the Slant community recommends Banana Pi for most people. In the question“What are the best single-board computers?” Banana Pi is ranked 27th while ODROID-W is ranked 29th.
Ranked in these QuestionsQuestion Ranking
Pro Software compatible with the Raspberry Pi
ODROID-W is compatible with the Raspberry Pi at least as far as software goes. It can run any software built for the Pi.
Pro Amazing heat dissipation
The ODROID-W has some great heat dissipation. From studying the heat of the heatsink, the maximum temperature registered was 37 degrees Celsius, and that was registered when the board was doing a lot of unpacking through apt-get. Normally the temperature is even lower than that.
Pro Can fit most Pi cases
Since it's built to emulate the Raspberry Pi, it's roughly the same shape albeit a bit smaller. But even then it should be able to fit most Raspberry Pi cases.
Pro Additional keys for booting or shutting down
Pro SATA port
Pro Official support for multiple Desktop-version Linux distros
Banana Pi officially supports Fedora, Arch, Lubuntu and openSUSE. It also can be used with Raspbian (Debian derivative) or Android.
Pro Onboard Wi-Fi
Most models have an onboard Wi-Fi.
Pro Excellent compatibility with Raspberry Pi software
Other than having a port of Raspbian (the official OS for Raspberry Pi) available for use with full capabilities, Banana Pi can also use many applications that were originally written for Raspberry. One of these is WiringPi, a C/C++ library which gives easy access to Raspberry's I/O with a strong Arduino flavor. But that is just one example of the many open source projects being ported to Banana Pi.
Con No on-board Ethernet
The ODROID-W has no on-board Ethernet port available, however this can be fixed by using a docking board which has an Ethernet jack.
Con Needs a multi-USB hub
Since it only has a USB host connector available for a full-sized port, you most certainly will need a multi-USB hub to connect more than one external devices to the board.
Con Bad software support
Con Does not fit most Raspberry Pi cases, even though it's where it clearly has gotten the inspiration from
The Banana Pi is pretty noticeable a Rapberry Pi lookalike and the name does not hide this information either. Unfortunately it's a bit larger than the Raspberry Pi, making it very hard to fit into most Raspberry Pi cases.
Con No off-the-shelf camera modules
The A20 chip that the Banana Pi uses lacks a true Camera Serial Interface implementation, instead it uses a parallel camera interface. The problem with this is that there are no off-the-shelf camera modules that support this and can connect to the Banana Pi, but it should be mentioned that the makers of Banana Pi have promised to create a camera module that is supported by it.
