 * It requires a regulated 5VDC 2A power supply with a 4.0mm(ext. diameter)x1.7mm (int. diameter) barrel plug. The outside of the plug is ground.

 * Is there a link to the original ~70MB image that I can download?

 * What are the serial port settings?
 * There is one USB-serial cable in the cubieboard package. The four color lines of the cable are: White, Black, Red, Green.
 * The definition of the lines are: RED +5v, BLACK gnd, GREEN rx, WHITE tx.
 * Connect the black one to GND pin on the board, GREEN one to RX pin, WHITE one to TX pin.
 * Don't connect the RED one if it's 5V, it may not break the board but you had better not do that.
 * The standard package doesn't contain the serial cable, the rich package contains the serial cable.


 * Is it possible to power the Cubieboard via USB?
 * Yes


 * Is it possible to connect a SSD drive on Cubieboard?
 * Yes


 * I notice there is an IR interface on Cubieboard. How do I use it?
 * Please refer to the A10 User Manual section 19 IR Interface, the driver is already in the kernel, an input device that can work with normal ir remote. IR test is one of the test of cubieboard before shipping.


 * What is the spacing between the contacts of the pin headers?
 * 2.0mm


 * Does cubieboard support sata port multipliers and what is the max limit of a sata hdd?
 * A10 does not support port multipliers. Storage limit is per SATA 2.0 specifications, 48 bit LBA addressing.or 128 PiB.
 * You'd need a sata cabinet that does raid itself. So the multiplier needs to emulate a single drive. The host system Cubiboard then sees only a single sata disk, with whatever capacity your chosen raid level gives you.


 * There is a SATA connector. What harddrives will work?
 * The onboard 5V SATA power connector is only for 2.5" HDD.
 * For 3.5" HDD usage you need a power supply that supplies 5v + 12v, and power the cubieboard from 5v and hdd from 5v + 12v.
 * The option of powering both separately from the same power supply is always possible.


 * OK, I have my Cubieboard now! Where is a good place to start?
