Pololu Micro Serial Servo Controller (assembled)
At only 0.91" x 0.91", the Pololu micro serial servo controller is the smallest, highest-performance serial servo controller you'll find. With individual speed and range control of eight servos and over 12 bits of resolution, this tiny device has the features you would expect in a latest-generation design, all for a surprisingly affordable price.
The Pololu micro serial servo controller (SSC) is a very compact solution for controlling up to eight radio control (RC) servos from a computer or microcontroller. The controller measures just 0.91" x 0.91", yet it is one of the most full-featured servo controllers available. Each servo speed and range can be controlled independently, the baud rate is detected automatically over a 1200-38400 bps range, 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 1/4-scale servos.
All components included the Pololu Micro Serial Servo Controller Kit.
The micro serial servo controller is available in two configurations: fully assembled with all connector pins, as shown in the main product pictures, and as a partial kit. The kit, shown to the left, has all of the surface-mounted components assembled. You can save some money and solder in the included pins yourself, or you can leave them out altogether and solder in your servos directly for a really compact installation.
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 labelled, 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.
