Building a Hobby Servo Controller – Part 1
A PCA9685 servo controller set to output pulses every 50Hz, can only resolve 390 steps due to its 12-bit resolution. To improve this, the pulse rate could be increased, but even at 60Hz, the PCA9685 can only resolve 475 steps. A better quality servo than my SG-5010 may well have a resolution in excess of 500 steps.Web
