However, you can squeeze an ARM7 into a much smaller space than that:

The site says the board can also read back and digitize the PWM signal (position feedback) that is provided by KHR and Robonova servos. It can also interface with gyros and accelerometers.

Can anyone with experience in CPLDs shed some light over how this little board would provide a significant upgrade to KHR, Robonova and Bioloid boards?
