Compact Multi-Channel Servo Driver Board for Controlling 200 Servos with Microcontroller

I want to drive hundreds of servos with a single microcontroller. And the problem is that the hardware has to be as tiny as possible.  Is there a multi-channel servo driver board that I can use keeping the size constraint in mind???  The control circuitry has to be palm sized device

Hi Muhammad-Wow- That's asking a lot!  I don't think you could even fit 200 of the 3-pin connectors normally used on servos in a palm-sized device, much less all of the other parts required.I'm thinking that this will be a job for a big FPGA (field programmable gate array).  You could possibly set it up as a coprocessor controlled by SPI or I2C and let it do the "heavy lifting" while the microcontroller just tells it what to do.Sorry to say I'm not an expert on these, but Max is.  Perhaps he will comment.-Rick

FPGA is a great option! My idea was to  use a simple microcontroller and use multiplexers on all of its I/Os. I also found schematics for such a device with 64 channels. So I was thinking that I could expand the same thing to 200 or 300 channels as per need.

Also size isnt the only problem. The solution has to be fast because the values on all the outputs will be changing continuously and have to be plotted  in real time with as little delay as possible.Will the fpga be faster than what I came up with?
