Hello,
Is it possible to stack multiple servo controllers on each other?
Can they be used to control multiple servo motors?

It appears that they have a few address jumpers that will allow you to set the I2C address, so yes I would say you can have as many of these running as you like.
If you mean physically stack them, well you can figure that out as easily as anyone I guess.
There's 6 address jumpers. => 64 possible addresses. (26)
And if 64 chips is not enough for you there are tricks to allow you to use more.

I would love to see the project that 1,024 servos is not enough for.
Actually, you can be the one to design it. It's called kinetic art. Motors are used ina sort of "swarm" mode where a computer (arduino) synchronizes them , resulting in a "wave" like motion that can be hundreds of stepper motors pulleys that raise and lower ornaments or a thousands of servos controlling objects via linkage rods similar to an airplane rudder or horizontal stabilizer or even small pulleys raising and lowering objects suspended by wire or thread.
They could be rotating flowers little bird heads turning or anything. The uC can create wave like motion or synchronization. For example, suppose
you have a thousand little squares , black on one side and white on rhe other that can be flipped over via linkage attached to a servo arm on pivot hinge. The program can create patterns formed by the contrasting colors at varrying speeds that increase and decrease exponentially and then
suddenly all change the same color and then start another pattern sequence. This is the latest fad and takes endless forms. There's literally no end to the variations possible.
