Note: this version has been replaced by the Pololu serial 8-servo partial kit.
The Pololu serial 8-servo controller allows you to control up to eight RC servos with almost any robot controller or computer. The interface to the servo controller is a standard RS-232 serial port or a TTL-level serial line, using any baud rate between 1200 and 38400 baud. Multiple 8-servo controllers can be connected to a single serial line to control up to 128 servos independently. This servo controller is compatible with our serial 16-servo controller, micro dual serial motor controller, and dual serial motor controller.
This servo controller is also compatible with the Scott Edwards MiniSSC II servo controller and any software written for it. You can purchase the servo controller as a kit so you can assemble it yourself (which requires soldering), or you can purchase a preassembled servo controller that is soldered and tested for you.
