Jessie, if one of your primary interests is ROS i think you should start looking at other options in boards. while the pine64 seems to do well with the rpi GPIO expansion bus, the I2C expansion board is at the moment being reported as having problems. the bus header is reportedly ok but the expansion board is reportedly not ok. now, pine64 may be able to quickly resolve the board issues but in my opinion if it is not an issue that can be quickly resolved it might be a source of frustration for your ROS project. i'm not saying to immediately jump to another board but to start looking at other options might help. again, this is IF your primary interest is in ROS development. welcome to the forum.
