The default composite video is lame for most GUI based applications. The HDMI DIP (about $12 US more) doesn't work well over 640x480 resolution for anything serious. This is OK with me since most of my projects are headless, but if you plan on using it for a cheap video streamer, good luck.
At $9 a piece, $12 for shipping costs more than the CHIP itself. I ended up ordering 5 CHIPs at a time to spread out the shipping costs. Thus each CHIP costs around $11.40 US shipped. If I knew I'd like them so much I would have ordered 12 the first time for a $10 CHIP shipped :) Shipping takes
The ODROID GPIO pins operate at 1.8V which means that it cannot support most accessories and sensors on the market which operate at 3.3V or 5V. But this can be fixed for the XU4 with the XU4 Shifter Shield which adapts them for voltages used in the market. It comes at an extra cost of $18 though.
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 mak...
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.
The Udoo has a separate ARM Cortex-M3 CPU which is the same found on the Arduino Due in addition to its other ARM i.MX6 Freescale CPU which runs either Linux or Android. Making the Udoo perfect for hybrid projects that need both Linux and Arduino capabilities.
Both Android and Ubuntu images lack some useful software which would be installed out-of-the-box for most Android or Linux devices. For example in Android it lacks the Play Store app and other Google apps. These can of course be installed but need to be done so manually (at least the Play Store) by
Other than releasing all drivers as open source, Intel has also made the schematics of the board available to download, this way hackers can give it a try and build anything they want without restrictions.
Because it has only two USB ports, one of which to be used for charging, a multi-USB hub is needed to connect a keyboard and mouse which are the absolute minimal external devices to be able to use and configure the MinnowBoard.
There's only one USB port available for peripherals, which is a bit annoying considering how two USB ports is a minimum to have a keyboard and a mouse hooked up without having to use a powered USB hub.
The cheapest version of the Humingboard Gate doesn't have a built-in Wifi card. You can either buy it separately as an add-on or you can buy a more expensive version of the Humingboard Gate which has a built-in Wifi card.
Starting at $70, prices can go up to $235 depending on the model and the components that users choose to add to the board. For these prices it's rather expensive relative to other single board computers.
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 pro...
The C2 uses 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.
