So I connect those make of gyroscope into Digital. Thank you for the information.
Not specifically a digital but the SPI, which uses 4 wires to talk. Then needs a chip select line for each chip you want to talk to. Note you can only talk to 1 chip at a time, though you might only need to for a fraction of a second
How about power? From what I can tell there doesn't seem to be more than one power output and I plan to use multiple sensors.
well your gonna need around 3V for the chips, so with a regular arduino you might burn them out unless you do somethign to cut out the 5V of the arduino. An arduino pro though they make a 3.3v model (that means the digital pins run at 3.3V) that would be perfect
Also, for straight powering. even though theres only 1 3V pin on an arduino. all the Vin's on your gyro will hook into that. Ill use https://www.sparkfun.com/products/10612
as an example, since its a similar unit to what you want.
all the VCCs on the gyro (in this case on the breakout board) will go to 3 volts on the arduino to power the chip up itself.
All the GNDs on the gyro will go to the arduino's ground.
SCL is the Serial Clock, which connects to one of the SPI pins (read this about SPI http://arduino.cc/en/Reference/SPI
Same with SDA and SDO (the data lines, they also correspond to the MOSI and MISO lines talked about in the SPI reference. More on that later
The CS pin is chip select. When this is pulled to ground, it allows data to go between the chip and the arduino
The last 2 spots on the board I linked are for the other interface you could use called I2C. I have avoided using that however so I can't help you use that at all.
