Connecting Lapdock
« on: September 02, 2013, 10:35:42 pm »
I am holding off purchasing a cubieboard2 until I figure out what accessories to purchase for it. Because using parts from my bricked netbook seems too difficult, I am returning to the option of buying a Motorola Atrix lapdock. What cables do I need to purchase to connect the lapdock to cubieboard2? Are they available in a short length? Everything needs to fit inside my backpack.

I'm still waiting for two Lapdocks to do the same for my father (Raspberry Pi) and for my brother (Cubieboard).
I'll follow this tutorial:
Since they both use HDMI it should not make a difference on that side.
The only difference is the power supply. Raspberry Pi uses micro usb, while the Cubieboard is using either mini usb or a normal dc connector.
If you make a cable with a bare dc connector you should double check the polarity. Positive (red) should go to the center of the plug and negative (black) should go to the outside.
The easiest way would be to cut the usb-to-dc-cable which was delivered together with the cubieboard. The plug has the right size and I expect that the cables inside are red and black so you just have to solder red to red and black to black.

If you don't want to solder you could follow this tutorial:
There you can use cubieboards usb-to-dc-cable instead of the usb-to-micro-usb-cable.
There is also a good hint for choosing the right hdmi-plug/-cable. It should be small or it should have the right shape.

On this picture it looks like the Lapdock 100 is also using micro-hdmi and micro-usb.
So it should work just like the same as with the first Lapdock.
