user19212: What is the smallest size digital 3-axis gyroscope pcb compatible with an arduino that I can buy or maybe make if its simple enough. I need one really really tiny probably around 0.8x0.1x0.5 (doesn't have to be that small but the smaller the better).
Thanks,

user19264: Arduino accesories are generally large because they are meant to be easy to use. mpu-6050 is a good example and you can find many decent breakout boards for it. But if you really want it to be very small, you should consider a custom solution for your problem like designing a PCB that holds both the microcontroller and the accelerometer. 

user11568: smallest board is no board.  pick a small BGA or LGA shaped accelerometer and superglue it face down to the arduino board then solder fine wires beween the chip terminals and arduino terminals.
search digikey for 'spi accelerometer'
