Hi
I'm considering using a servo to control the angle of a small (100g) solar array. This is for a demo project, in which I'll be using a Microsemi SmartFusion FPGA to drive the control signal of a small (Hitec HS-55 or Futaba S-3001/3004) servo.
The FPGA IO's cannot go higher than 3.3V, 12mA
The Hitec site says that 3-5V peak-to-peak is enough for the control signal - this is good.
However, I'm concerned about the input capacitance of the servo control input - is there any data on what this ranges between? What do typical users of these (or other small and cheap) servos drive the control inputs with?
Thanks for any help
