Pololu Micro Maestro 6-channel Servo Controller. Most microcontrollers I have used can control servos directly. Delegating the responsibility does free up the microcontroller. I have plans for the microcontrollers to do more calculations. The Maestro looks a bit dated with a USB mini-B connector but works fine. I did need to install the Pololu Maestro Control Center software on a laptop in order to set the Maestro Serial mode. This software was required to turn on the CRC message checker.
