yes, if you are using techFX tools to do your sequences, then you can use 2 servos on IO16 and IO17 0.5-2.5 mS in 10 uSec increments.
if you are writing your own code, then u could use more pins as needed.
also you can expand it with a devantech SD21 servo controller (~30 bucks) which will then allow you to use techFX tools and use 22 servos total!!! thats using 1 techFX controller with 1 devantech I2C controller connnected also. (total cost is roughly 80 bucks or so).. not bad for controlling 22 servos and all the other IO also!!!
bear in mind you can hook upto 6 devantech I2C servo boards upto it, or mix and match i2C modules as necessary.
prop controller, featuring 31 io and free software so u can program it with no code writing!! dual voltage feature also which means less power supplies.
