Description: The Pololu micro serial servo controller (SSC) is a very compact solution for controlling up to eight RC servos from a computer or microcontroller. Each servo speed and range can be controlled independently and multiple units can be daisy-chained on one serial line to control up to 128 servos. Three status LEDs and an integrated level converter for RS-232 applications get you up and running quickly. The micro serial servo controller is dwarfed by even a standard servo, but it can control any standard RC servos, including giant ¼-scale servos.
This servo controller supports two separate communication protocols. One protocol is compatible with our other serial servo controllers and our serial motor controllers, and it offers individual range and speed control for each servo. This servo controller is also compatible with the Scott Edwards MiniSSC II servo controller and any software written for it.
The back side of the board has all of the ports labeled, and two mounting holes allow you to secure the controller to your project. The logic supply and the servo supply can be tied together for single-battery operation, or the on-board voltage regulator allows the logic supply to be as high as 16V.

This is a handy little board for running a bunch of servos, but it doesn’t fail gracefully. One wrong byte over the serial port, the red LED comes on, and the entire device stops working (until you reset it).
Like the user guide says, do not use this device for anything where failure could lead to damage or injury.
