Notice that, this module should be **3.3v powered**, because Cubieboard's TTL VCC is 3.3v. | * Cubieboard side: A serial-bluetooth module, to be attached to Cubieboard's TTL serial port.

| * method two needs more hardware, and the boot message such as U-Boot message could never show up, because the USB serial console won't work until the kernel boots up. The advantage is USB connection is much easier and could be expanded by USB hubs. | * method two needs more hardware, and the boot message such as U-Boot message could never show up, because the USB serial console won't work until the kernel boots up.
